    Peptides have acquired increasing interest as promising therapeutics, particularly as anticancer alternatives during recent years. They have been reported to demonstrate incredible anticancer potentials due to their low manufacturing cost, ease of synthesis and great specificity and selectivity. Hepatocellular carcinoma (HCC) is among the leading cause of cancer death globally, and the effectiveness of current liver treatment has turned out to be a critical issue in treating the disease efficiently. Hence, new interventions are being explored for the treatment of hepatocellular carcinoma. Anticancer peptides (ACPs) were first identified as part of the innate immune system of living organisms, demonstrating promising activity against infectious diseases. Differentiated beyond the traditional effort on endogenous human peptides, the discovery of peptide drugs has evolved to rely more on isolation from other natural sources or through the medicinal chemistry approach. Up to the present time, the pharmaceutical industry intends to conduct more clinical trials for the development of peptides as alternative therapy since peptides possess numerous advantages such as high selectivity and efficacy against cancers over normal tissues, as well as a broad spectrum of anticancer activity. In this review, we present an overview of the literature concerning peptide's physicochemical properties and describe the contemporary status of several anticancer peptides currently engaged in clinical trials for the treatment of hepatocellular carcinoma.

    Medicinal chemists have continuously shown interest in new curcuminoid derivatives, diarylpentadienones, owing to their enhanced stability feature and easy preparation using a one-pot synthesis. Thus far, methods such as Claisen-Schmidt condensation and Julia- Kocienski olefination have been utilised for the synthesis of these compounds. Diarylpentadienones possess a high potential as a chemical source for designing and developing new and effective drugs for the treatment of diseases, including inflammation, cancer, and malaria. In brief, this review article focuses on the broad pharmacological applications and the summary of the structure-activity relationship of molecules, which can be employed to further explore the structure of diarylpentadienone. The current methodological developments towards the synthesis of diarylpentadienones are also discussed.

    Theranostics has the potential to revolutionize the diagnosis, treatment, and prognosis of cancer, where novel drug delivery systems could be used to detect the disease at an early stage with instantaneous treatment. Various preclinical approaches of nanoemulsions with entrapped contrast and chemotherapeutic agents have been documented to act specifically on the tumor microenvironment (TME) for both diagnostic and therapeutic purposes. However, bringing these theranostic nanoemulsions through preclinical trials to patients requires several fundamental hurdles to be overcome, including the in vivo behavior of the delivery tool, degradation, and clearance from the system, as well as long-term toxicities. Here, we discuss recent advances in the application of nanoemulsions in molecular imaging with simultaneous therapeutic efficacy in a single delivery system.

    Regardless of advances in detection and treatment, breast cancer affects about 1.5 million women all over the world. Since the last decade, genome-wide association studies (GWAS) have been extensively conducted for breast cancer to define the role of miRNA as a tool for diagnosis, prognosis and therapeutics. MicroRNAs are small, non-coding RNAs that are associated with the regulation of key cellular processes such as cell multiplication, differentiation, and death. They cause a disturbance in the cell physiology by interfering directly with the translation and stability of a targeted gene transcript. MicroRNAs (miRNAs) constitute a large family of non-coding RNAs, which regulate target gene expression and protein levels that affect several human diseases and are suggested as the novel markers or therapeutic targets, including breast cancer. MicroRNA (miRNA) alterations are not only associated with metastasis, tumor genesis but also used as biomarkers for breast cancer diagnosis or prognosis. These are explained in detail in the following review. This review will also provide an impetus to study the role of microRNAs in breast cancer.

    Majority of the representative drugs customarily interact with multiple targets manifesting unintended side effects. In addition, drug resistance and over expression of the cellular efflux-pumps render certain classes of drugs ineffective. With only a few innovative formulations in development, it is necessary to identify pharmacophores and novel strategies for creating new drugs. The conjugation of dissimilar pharmacophoric moieties to design hybrid molecules with an attractive therapeutic profile is an emerging paradigm in the contemporary drug development regime. The recent decade witnessed the remarkable biological potential of 1,3,5-triazine framework in the development of various chemotherapeutics. The appending of the 1,3,5-triazine nucleus to biologically relevant moieties has delivered exciting results. The present review focuses on 1,3,5-triazine based hybrid molecules in the development of pharmaceuticals.

    INTRODUCTION: The effectiveness of conventional cancer chemotherapy is hampered by the occurrence of multidrug resistance (MDR) in tumor cells. Although many studies have reported the development of novel MDR chemotherapeutic agents, clinical success is lacking owing to the high associated toxicity. Nanoparticle-based delivery of chemotherapeutic drugs has emerged as alternative approach to treat MDR cancers via exploitation of leaky vasculature in the tumor microenvironment. Accordingly, functionalization of nanoparticles with target specific ligands can be employed to achieve significant improvements in the treatment of MDR cancer. Areas covered: This review focuses on the recent advances in the functionalization of nanocarriers with specific ligands, including antibodies, transferrin, folate, and peptides to overcome MDR cancer. The limitations of effective ligand-functionalized nanoparticles as well as therapeutic successes in ligand targeting are covered in the review. Expert opinion: Targeting MDR tumors with ligand-functionalized nanoparticles is a promising approach to improve the treatment of cancer. With this approach, higher drug concentrations at targeted sites would be achieved with lower dosage frequencies and reduced side effects in comparison to existing formulations of chemotherapeutic drugs. However, potential toxicities and immunological responses to ligands should be carefully reviewed for viable options in for future MDR cancer treatment.

    Dendrimers are novel nanoarchitectures with unique properties including a globular 3D shape, a monodispersed unimicellar nature and a nanometric size range. The availability of multiple peripheral functional groups and tunable surface engineering enable the facile modification of the dendrimer surface with different therapeutic drugs, diagnostic agents and targeting ligands. Drug encapsulation, and solubilizing and passive targeting also equally contribute to the therapeutic use of dendrimers. In this review, we highlight recent advances in the delivery of anticancer drugs using dendrimers, as well as other biomedical and diagnostic applications. Taken together, the immense potential and utility of dendrimers are envisaged to have a significant positive impact on the growing arena of drug delivery and targeting.

    BACKGROUND: The Notch pathway is an evolutionarily conserved, intercellular signalling system which is present in all multicellular organisms and mammals. The Notch pathway plays an important role in the embryonic development as it controls cell proliferation, cell differentiation and binary cell fate decisions.

    OBJECTIVE: In the present review, we highlight the Notch signalling pathway components i.e. Notch receptors, ligands, effector, and their regulators. We also discuss the tumor biology of the Notch pathway involved in various cancers.

    RESULTS: Interestingly, the Notch signalling pathway is dysregulated in many cancers. Notch may serve as oncogene or tumor suppressor and plays an important role in cancers of the liver, pancreas, endometrium of uterus, ovary, prostate, bladder and colon. The activation of Notch pathway plays a vital role in the progression of some cancer. In addition, Notch pathway activation was also shown to drive chemoresistance in cancer, as well. Chemotherapeutically, combined NOTCH1 inhibitor synergistically attenuated chemotherapy-enriched cancer stem cell population both in vitro and in vivo. This may prove to be beneficial in the treatment of cancer.

    CONCLUSION: The Notch inhibitors possess anti-proliferative effects on cancer, thereby serving as a new treatment for cancer.

    Oral mucosal melanoma is rare and more aggressive than cutaneous melanoma. Hard palate and maxillary alveolar crest are most commonly involved. Multidisciplinary team approach is necessary for successful management of this tumor. The main treatment modality is surgical resection, which usually results in impaired mastication, deglutition, speech, oral competence and significant cosmetic deformity. Here, a rare case of oral mucosal melanoma of mandibular gingiva in a 44-year man is reported, who was treated by en-block mandibular resection followed by adjuvant therapy with high dose interferons (IFN) - 2b. Following two weeks of healing period, prosthetic rehabilitation of the patient was done with an interim removable denture prosthesis, which effectively limited the unfavourable effects of surgery and helped him in resocialisation.

    Since its discovery, cisplatin has become the key drug in chemotherapy for cancers. Nevertheless, chemoresistance in cancers has become an impediment in using cisplatin for cancer treatment. The resistance toward cisplatin is multifaceted as it involves multiple cellular pathways. Ever since the knowledge of long noncoding RNAs as modulators of various molecular pathways came to light, the interest in the biological function of lncRNAs as biomarkers has increased dramatically. Numerous studies have reported the link between the dysregulation of lncRNAs and drug resistance in cancers. More importantly, several lncRNAs were found to be vital in regulating cisplatin resistance. Therefore, this review summarizes the recent efforts in linking between cisplatin resistance and different types of lncRNAs.

    Lung cancer is a highly invasive and prevalent disease with ineffective first-line treatment and remains the leading cause of cancer death in men and women. Despite the improvements in diagnosis and therapy, the prognosis and outcome of lung cancer patients is still poor. This could be associated with the lack of effective first-line oncology drugs, formation of resistant tumors and non-optimal administration route. Therefore, the repurposing of existing drugs currently used for different indications and the introduction of a different method of drug administration could be investigated as an alternative to improve lung cancer therapy. This review describes the rationale and development of repositioning of drugs for lung cancer treatment with emphasis on inhalation. The review includes the current progress of repurposing non-cancer drugs, as well as current chemotherapeutics for lung malignancies via inhalation. Several potential non-cancer drugs such as statins, itraconazole and clarithromycin, that have demonstrated preclinical anti-cancer activity, are also presented. Furthermore, the potential challenges and limitations that might hamper the clinical translation of repurposed oncology drugs are described.

    The current study is a review of the literature on patients with diabetes who are diagnosed with colorectal cancer (CRC), encompassing recent research on CRC and the molecular level changes occurring in these patients on the basis of varying environmental as well as non-environmental factors. It has been noted that nearly 50% of all patients undergo the systemic treatment module; however, most of them exhibit drug resistance. In addition, targeted gene therapy has also been used in treatment but has been found to be effective only in patients with a specified molecular profile (or else this might lead to an increased risk of developing resistant mutations). This has led to increasing interest among researchers in finding innovative treatment options. Metformin, a biguanide, has been widely used in treating diabetes. The drug has been reportedly used in cases of hypothesis-generating retrospective population studies of diabetic patients showing reduced incidence of cancer. Metformin helps in reduction of excess insulin levels that possess various effects on cell signaling and metabolism. Nonetheless, there is need for an in-depth study on its molecular mechanism to fill any existing research gaps.

    Benzyl isothiocyanate (BITC) is one of the common isothiocyanates found in cruciferous vegetables such as broccoli, cabbage or watercress. Preclinical studies report of its effectiveness in the prevention and treatment against several cancers. This review aims to report and discuss findings on anticancer activities of BITC and its modes of action against 14 types of cancer. A literature search was conducted using the keywords "BITC" and "anticancer" from PubMed, Google Scholar and CINAHL Plus to obtain relevant research articles. This review highlights the anticancer efficacy of BITC through modulation of various signaling pathways involved in apoptosis, cell proliferation, cell cycle arrest, metastasis, angiogenesis, autophagy and the effects of BITC in combination with other drugs. With the available pharmacology evidence, we conclude that further studies are needed to validate its effectiveness in humans for further development and translation into prophylaxis or therapy by promoting optimal therapeutic effects and minimizing toxicity in cancer treatment.

    BACKGROUND: Recent reports indicate that the tumor microenvironment plays a pivotal role in cancer development and progression, leading to a paradigm shift in the way cancer is studied and targeted. In contrast to traditional approaches, where only tumor cells are targeted for the treatment, an emerging approach is to develop therapeutics which target the tumor microenvironment while complementing or enhancing current treatments. Legumain (LGMN) is a newly identified target which is highly expressed in the tumor microenvironment and in tumor cells, and holds potential both as a biomarker and as a therapeutic target.

    CONCLUSION: This review will be the first to summarize the expression of LGMN in common cancers, as well as its roles in tumorigenesis and metastasis. This review also discusses the current developments and future prospects of targeting LGMN through the development of DNA vaccines, azopeptides, small molecule inhibitors and LGMN activated prodrugs, highlighting the potential of LGMN as a target for cancer therapeutics.

    In this study, a series of 20 structurally similar vanilloids (Vn) were tested for their antiproliferative effects against 12 human cancer cells: human breast (MCF-7 and MDA-MB-231), cervical (HeLa), ovarian (Caov-3), lung (A549), liver (HepG2), colorectal (HT-29 and HCT116), nasopharyngeal (CNE-1 and HK-1), and leukemic (K562 and CEM-SS) cancer cells. Among all the tested vanilloids, Vn16 (6-shogaol) exhibited the most potent cytotoxic effects against human colorectal cancer cells (HT-29). The apoptotic induction effects exhibited by Vn16 on HT-29 cells were confirmed using dual staining fluorescence microscopy and enzyme-linked immunosorbent assay. The effects of Vn16 on regulation of 43 apoptotic-related markers were determined in HT-29. The results suggested that 8 apoptotic markers (caspase 8, BAD, BAX, second mitochondrial-derived activator, caspase 3, survivin, bcl-2, and cIAP-2) were either upregulated or downregulated. These results further support the chemopreventive properties of foods that contain vanilloids.

    Diabetes mellitus (DM) is frequently increased in many countries and become a serious health problem worldwide. Diabetes is associated with dysfunction of different organs such as heart, eyes, blood vessels, nerves, and kidneys. There is a strong connection between diabetes and cancer. Metformin is one of the most commonly prescribed oral antidiabetic medicines and it is suggested as the first-line therapy due to its comparatively safe, inexpensive, effective and well-tolerated. Some of the in vitro and in vivo investigations proved that metformin may have a direct anticancer action by preventing the proliferation of malignant cells and formations of the colony, inducing arrest of cell cycle and apoptosis and suppressing tumor growth. The antiproliferative mechanism of metformin alone or in combination with various chemotherapeutic agents is complex and involves several beneficial roles. In this regard, clinical studies are required to explain these roles. In the coming future, the use of metformin, alone or in combination with current chemotherapy, might be a conventional approach to effectually manage lung cancer. This mini-review provides a critical overview of currently available clinical trials investigating the effects of metformin in lung cancer.

    Despite the excellent efficacy and improved clinical responses obtained with imatinib mesylate (IM), development of resistance in a significant proportion of chronic myeloid leukemia (CML) patients on IM therapy have emerged as a challenging problem in clinical practice. Resistance to imatinib can be due to heterogeneous array of factors involving BCR/ABL-dependent and BCR/ABL-independent pathways. Although BCR/ABL mutation is the major contributory factor for IM resistance, reduced bio-availability of IM in leukemic cells is also an important pharmacokinetic factor that contributes to development of resistance to IM in CML patients. The contribution of polymorphisms of the pharmacogenes in relation to IM disposition and treatment outcomes have been studied by various research groups in numerous population cohorts. However, the conclusions arising from these studies have been highly inconsistent. This review encompasses an updated insight into the impact of pharmacogenetic variability on treatment response of IM in CML patients.

    Leflunomide (LF) represents the prototype member of dihydroorotate dehydrogenase (DHODH) enzyme inhibitors. DHODH is a mitochondrial inner membrane enzyme responsible for catalytic conversion of dihydroorotate into orotate, a rate-limiting step in the de novo synthesis of the pyrimidine nucleotides. LF produces cellular depletion of pyrimidine nucleotides required for cell growth and proliferation. Based on the affected cells the outcome can be attainable as immunosuppression, antiproliferative, and/or the recently gained attention of the antiviral potentials of LF and its new congeners. Also, protein tyrosine kinase inhibition is an additional mechanistic benefit of LF, which inhibits immunological events such as cellular expansion and immunoglobulin production with an enhanced release of immunosuppressant cytokines. LF is approved for the treatment of autoimmune arthritis of rheumatoid and psoriatic pathogenesis. Also, LF has been used off-label for the treatment of relapsing-remitting multiple sclerosis. However, LF antiviral activity is repurposed and under investigation with related compounds under a phase-I trial as a SARS CoV-2 antiviral in cases with COVID-19. Despite success in improving patients' mobility and reducing joint destruction, reported events of LF-induced liver injury necessitated regulatory precautions. LF should not be used in patients with hepatic impairment or in combination with drugs elaborating a burden on the liver without regular monitoring of liver enzymes and serum bilirubin as safety biomarkers. This study aims to review the pharmacological and safety profile of LF with a focus on the LF-induced hepatic injury from the perspective of pathophysiology and possible protective agents.
