Abstract

Mulberry leaf is a traditional herb and predicted has ecdysteronecompound which act as antihyperglicemid. Glybenclamide is a synthetic medicine used to cure diabetes mellitus type 2. The leaf reported as competitive inhibitor of CYP3A4 enzyme, which metabolizingglibenclamide. However, in many cases, combination of herbs with synthesis drugs causes interaction if used at the same time. This research aimed to see interaction of ethanol mulberry leaf extract with glibenclamide through CYP3A4 gene expression in HepG2 cell culture.Sample of mulberry extract, glibenclamide, and combination both sample were tested into cell HepG2 culture. Then RNA were isolated and purification using real time PCR to see the gene CYP3A4 expression. As a result, mulberry extract acts as inhibitor enzyme CYP3A4, while glibenclamide is enzyme substrate.The combination of mulberry and glibenclamide showed increased of expression of CYP3A4 gene, means greater enzyme produced, and lower medicine on blood plasma.

Abstract

The research was carried out to isolate and characterize of bioactive proteins from plant parts of Benincasa hispida (Thunb.) Cogn and to analyse of the toxicity and cytotoxicity of the proteins. The proteins were extracted with phosphate buffer saline, then they were precipitated using 80% saturated ammonium sulphate, continued with the dialysis  using pH 7 phosphate buffer. The dialysate was fractionated through gel filtration chromatography and characterized using SDS-PAGE. The toxicity of the proteins was analyzed through brine shrimp lethality test (BSLT), followed with cytotoxicity test using HeLa and K-562 cancer cell lines. Three bioactive protein fractions were isolated from the fruits, the seeds and roots. The lowest yield of proteins was 0.021% from the fruit, then 0.051% from the seed, while the highest was 0.54% from the root. All proteins were toxic on BSLT with LC50 within the range of 24-39 µg. Characterization of proteins using SDS-PAGE indicated the molecular mass of those proteins were approximately 17-29 kDa. The cytotoxicity test of the root protein showed that the protein could inhibit proliferation of HeLa cell up to 28.50% and K-562 cell up to 36.60% compared to that  of non treated cell.                   Key words: Benincasa hispida (Thunb.)
