    Zahidin NS, Saidin S, Zulkifli RM, Muhamad II, Ya'akob H, Nur H
    J Ethnopharmacol, 2017 Jul 31;207:146-173.
    PMID: 28647509 DOI: 10.1016/j.jep.2017.06.019
    ETHNOPHARMACOLOGICAL RELEVANCE: Acalypha indica is an herbal plant that grows in wet, temperate and tropical region, primarily along the earth's equator line. This plant is considered by most people as a weed and can easily be found in these regions. Although this plant is a weed, Acalypha indica has been acknowledged by local people as a useful source of medicine for several therapeutic treatments. They consume parts of the plant for many therapeutics purposes such as anthelmintic, anti-ulcer, bronchitis, asthma, wound healing, anti-bacterial and other applications. As this review was being conducted, most of the reports related to ethnomedicinal practices were from Asian and African regions.

    THE AIM OF THE REVIEW: The aim of this review is to summarize the current studies on ethnomedicinal practices, phytochemistry, pharmacological studies and a potential study of Acalypha indica in different locations around the world. This review updates related information regarding the potential therapeutic treatments and also discusses the toxicity issue of Acalypha indica.

    MATERIALS AND METHODS: This review was performed through a systematic search related to Acalypha indica including the ethnomedicinal practices, phytochemistry and pharmacological studies around the world. The data was collected from online journals, magazines, and books, all of which were published in English, Malay and Indonesian. Search engine websites such as Google, Google Scholar, PubMed, Science Direct, Researchgate and other online collections were utilized in this review to obtain information.

    RESULTS: The links between ethnomedicinal practices and scientific studies have been discussed with a fair justification. Several pharmacological properties exhibited certain potentials based on the obtained results that came from different related studies. Based on literature studies, Acalypha indica has the capability to serve as anthelmintic, anti-inflammation, anti-bacterial, anti-cancer, anti-diabetes, anti-hyperlipidemic, anti-obesity, anti-venom, hepatoprotective, hypoxia, and wound healing medicine. For the traditional practices, the authors also mentioned several benefits of consuming the raw plant and decoction.

    CONCLUSION: This review summarizes the current studies of Acalypha indica collected from many regions. This review hopefully will provide a useful and basic knowledge platform for anyone interested in gaining information regarding Acalypha indica.

  2. Fulltext Reversal of ampicillin resistance in MRSA via inhibition of penicillin-binding protein 2a by Acalypha wilkesiana

    The inhibitory activity of a semipure fraction from the plant, Acalypha wilkesiana assigned as 9EA-FC-B, alone and in combination with ampicillin, was studied against methicillin-resistant Staphylococcus aureus (MRSA). In addition, effects of the combination treatment on PBP2a expression were investigated. Microdilution assay was used to determine the minimal inhibitory concentrations (MIC). Synergistic effects of 9EA-FC-B with ampicillin were determined using the fractional inhibitory concentration (FIC) index and kinetic growth curve assay. Western blot experiments were carried out to study the PBP2a expression in treated MRSA cultures. The results showed a synergistic effect between ampicillin and 9EA-FC-B treatment with the lowest FIC index of 0.19 (synergism ≤ 0.5). The presence of 9EA-FC-B reduced the MIC of ampicillin from 50 to 1.56 μg mL(-1). When ampicillin and 9EA-FC-B were combined at subinhibitory level, the kinetic growth curves were suppressed. The antibacterial effect of 9EA-FC-B and ampicillin was shown to be synergistic. The synergism is due the ability of 9EA-FC-B to suppress the activity of PBP2a, thus restoring the susceptibility of MRSA to ampicillin. Corilagin was postulated to be the constituent responsible for the synergistic activity showed by 9EA-FC-B.

  3. Fulltext Prevention of cell-surface attachment and reduction of penicillin-binding protein 2a (PBP2a) level in methicillin-resistant Staphylococcus aureus biofilms by Acalypha wilkesiana
    Santiago C, Lim KH, Loh HS, Ting KN
    BMC Complement Altern Med, 2015;15:79.

    Formation of biofilm is known to enhance the virulence of methicillin-resistance Staphylococcus aureus (MRSA), which is associated with persistent infections in hospital settings. The biofilm layer essentially forms a protective barrier encapsulating the bacterial colony and thus reduces the effectiveness of chemotherapeutics. We have isolated 9EA-FC-B bioactive fraction from Acalypha wilkesiana Müll. Arg. that reverses ampicillin resistant in MRSA through inhibition of the antibiotic resistant protein, penicillin-binding protein 2a (PBP2a). In this study, we aimed to investigate the effects of 9EA-FC-B on MRSA biofilm forming capacity.
