Carvacrol, called CA, is a dynamic phytoconstituent characterized by a phenol ring abundantly sourced from various natural reservoirs. This versatile scaffold serves as a pivotal template for the design and synthesis of novel drug molecules, harboring promising biological activities. The active sites positioned at C-4, C-6, and the hydroxyl group (-OH) of CA offer fertile ground for creating potent drug candidates from a pharmacological standpoint. In this comprehensive review, we delve into diverse synthesis pathways and explore the biological activity of CA derivatives. We aim to illuminate the potential of these derivatives in discovering and developing efficacious treatments against a myriad of life-threatening diseases. By scrutinizing the structural modifications and pharmacophore placements that enhance the activity of CA derivatives, we aspire to inspire the innovation of novel therapeutics with heightened potency and effectiveness.
Doxorubicin (DOX) is a remarkable chemotherapeutic agent, however, its adverse effect on DOX-induced cardiotoxicity (DIC) is a rising concern. Recent research has identified carvacrol (CAR), an antioxidant and anti-inflammatory agent, as a promising natural compound for protecting against DIC. This study aims to investigate the potential cardioprotective effects properties of CAR in vitro and in vivo. The cardioprotective effect of CAR was assessed by pretreating H9c2 cells with non-toxic CAR for 24 h, followed by co-treatment with DOX (10 μM) for an additional 24 h. The cell viability was determined using an MTT assay. For the in vivo study, male Sprague-Dawley rats (200-250 g) were randomly divided into three groups: control, cardiotoxicity (DOX), and treatment (CAR + DOX) groups. CAR (50 mg/kg, BW) was administered orally to the CAR + DOX groups for 14 days. Then, a single dose of DOX (15 mg/kg/i.p, BW) was administered on day 15 for DOX and CAR + DOX groups. The rats were allowed to recover for 3 days before being sacrificed. Our results demonstrated that DOX (10 µM) significantly reduced H9c2 cell viability by 50% (p
