Anti-hepatitis C virus and synergistic potential of Syzgium cumine a bioassay guided screening in liver-infected hepatocytes.

Hepatitis C virus is still a global challenge affecting millions of carriers worldwide with the more devastating situation in developing countries. Present-day clinical manifestations are insufficient to tackle the increasing disease burden unaffordable cost, viral resistance and adverse effects of treatment. In this research, indigenous medicinal plants from Pakistan tested in bioassay guided manner on Huh-7 cell lines for their antiviral effect, synergism of purified fraction with interferon FDA approved drug regime, as the receptor for developing transfection model. The methanol extract of Syzgium cumine was observed against HCV through serum titter reduction in Quantitative Real Time PCR assay and the gene expression system, NS3protease inhibition was 76% and 51% against genotype 1a and 3a, respectively. More precisely the most active fraction SC14 was assessed in dose response assay and synergistic potential resulted in 50% reduction (EC50 Value) in HCV titer of genotype 1a and 3a at a concentration of 71.96 ± 8.67 µg and 31.75 ± 3.28 µg, respectively, at a concentration of 100 µg. As per our research work, the S. cumine extract has shown a promising effect on HCV genotypes 1a and 3a. Moreover the purified fraction S. cumine SC14 has a potential synergistic effect and ability to suppress the gene effect of NS3 during transfection in Huh-7 cells and GC/MS analysis reports the presence of Di-n-octyl phthalate (C24H38O4) which can be future direct-acting antiviral therapy against Hepatitis C virus.

In vitro antimutagenic, cytotoxic and anticancer potential of Fagonia indica phytochemicals.

Cancer is one of the most diagnosed and life threatening disease throughout the world. Nevertheless present day clinical management for cancers are surgery, radiations which are insufficient to contain the disease burden. In the past two decades, more than half of chemotherapeutic drugs developed are either directly or indirectly dependent on medicinal base phytocompounds or their derivative. The present study aims to provide the base for chemotherapeutic phytochemicals. Fagonia indica showed significant antimutagenic potential with reference to control IC50 values were calculated as 146.33±5.2µg/ml, TA100 (AZS) 105.33±4.0µg/ml, TA98 (2AA) 113.6±5.2µg/ml followed and TA98 (AZS) 112.6±4.4 in Ames test. For this reason, the antiproliferation effect of extracts on cancer cell lines was studied through resazurin fluorescence. On HepG-2 cell lines 50% cytotoxic concentration (CC50) of (FIWM) was recorded as 128.3±,2.43µg/ml. On the homo sapiens epithelial cell of lung tissue (A549), the high throughput instrumental analysis of Fagonia indica depicts maximum cytotoxic effect in 30hr. The electrical impedance displays the real-time evidence about qualitative apoptosis expressed. The impedance results were supported as palmitic acid from Fagonia indica virtually that inhibits Cyclin Dependent Kinase 2 (CDKs 2) in silico molecular docking studies. Fagonia indica extract possesses substantial antimutagenic, cytotoxic and anticancer activity which supports the potential of its phytochemicals for drug development.
