ABSTRACT
OBJECTIVE: Alternative medicine plays an important role today in searching for therapeutics for cancer and viral infection. So, a scientific validation to characterize constituents in the alternative medicines and therapeutic testing is warranted using modern instrumentation. METHODS: In the present study, an old herbomineral formulation, KanthaRasavillai [KRV], was characterized using UV-vis spectrometry, FT-IR, XRD, SEM, and TEM study. Also, In vitro and in vivo studies were done to evaluate their antiviral and anticancer activity. FT-IR and XRD studies revealed a cocktail of nanoparticles of mercury, magnetic oxide, cinnabar, and arsenic.ResultsBased on SEM, TEM, and XRD report, KRV contains nanoparticles in the size range of 9.1nm to 25.0 nm. FT-IR analysis exposed the presence of several anti-cancerous bioactive compounds.Further in vitro testing against HCV virus proved KRV to inhibit HCV virus a close relative to SARS-CoV-2. MTT assay confirmed the anticancer effect of KRV against Huh-7 and MCF-7 cell lines. CONCLUSION: The anticancer and antiviral properties in the ancient herbomineral drug with a cocktail of metal nanoparticles acknowledge the traditional medical practice as a pioneering approach for present-day ailments. However, the study concludes that the use of KRV depends on safety dosage and genuine preparation as described by ancient saints.
ABSTRACT
BACKGROUND: The increasing azole drug resistance in fungal pathogens poses a pressing threat to global health care. The coexistence of drug-resistant Candida albicans with tuberculosis patients and the failure of several drugs to treat C. albicans infection extend hospital stay, economic burden, and death. The misuse or abuse of azole-derived antifungals, chronic use of TB drugs, different immune-suppressive drugs, and diseases like HIV, COVID-19, etc., have aggravated the situation. So it is vital to understand the molecular changes in drug-resistant genes to modify the treatment to design an alternative mechanism. METHOD: C. albicans isolated from chronic tuberculosis patients were screened for antifungal sensitivity studies using disk diffusion assay. The multidrug-resistant C. albicans were further screened for molecular-level changes in drug resistance using MDR1 gene sequencing and compared with Gen bank data of similar species using the BLAST tool. RESULTS: The investigation proved that the isolated C. albicans from TB patients are significantly resistant to the action of six drugs. The molecular changes in MDR1 genes showed differences in seven nucleotide base pairs that interfered with the efflux pump.
