In an effort to improve potential hepatoprotective and anti-tumor activities, eight novel ursolic acid (UA) derivatives were designed and synthesized with substitution at positions of C-3, C-11 and C-28 of UA. Their structures were confirmed using IR, MS and (1)H-NMR and elemental analysis. Their in vitro cytotoxicity against various cancer cell lines (HeLa, SKOV3 and BGC-823) was evaluated by ...

1000-Grain weight and spikelet number per panicle are two important components for rice grain yield. In our previous study, eight quantitative trait loci (QTLs) conferring spikelet number per panicle and 1000-grain weight were mapped through sequencing-based genotyping of 150 rice recombinant inbred lines (RILs). In this study, we validated the effects of four QTLs from Nipponbare using chromos...

A series of novel 2-substituted indoline imidazolium salt derivatives has been prepared and evaluated in vitro against a panel of human tumor cell lines. The results suggest that the existence of a substituted benzimidazole ring and substitution of the imidazolyl-3-position with a naphthylacyl or 2-naphthylmethyl group were vital for modulating the cytotoxic activity. Compound 25 was found to b...

Mouse resources such as Collaborative Cross (CC), Outbred Stocks (OS), Hybrid Mouse Diversity Panel (HMDP), and Chromosome Substitution Strains (CSSs) have been instrumental to many progresses in the studies of complex traits genetics. We have established a population of chromosome 1 (Chr 1) substitution lines (C1SLs) in which donor chromosomes were derived from Chinese wild mice. Genome sequen...
