Objective: To study the chemical constituents in seeds of Cicer arietinum, so that to find bioactive natural products.
Method: Dried and sprouted seeds of C. arietinum were extracted with ethanol of various concentrations respectively, then isolated and purified by silica gel, macroreticular resin D 101, Sephadex LH -20 gel column chromatography, and structures of compounds were identified by spectral analysis.
Result: Nine compounds have been isolated and identified: 3-hydroxy-olean-12-ene (1), biochanin A-7-O-beta-D-glucoside (2), cerebroside (3), 1-ethyl-alpha-L-galactoside (4), uridine (5), adenosine (6), trytophan (7), biochanin A (8), fomononetin (9).
Conclusion: Compounds 1, 3, 4, 6, 7 were isolated from genus Cicer for the first time.

Single-point mutations are pivotal in molecular zoology, shaping functions and influencing genetic diversity and evolution. Here we study three such genetic variants of a mechano-responsive protein, cadherin-23, that uphold the structural integrity of the protein, but showcase distinct genotypes and phenotypes. The variants exhibit subtle differences in transient intra-domain interactions, which in turn affect the anti-correlated motions among the constituent β-strands.

: Cold-dampness diarrhea (CDD) is a common gastrointestinal disorder in children, characterized by diarrhea and intestinal barrier dysfunction. Weiling decoction (WLD) is frequently used in clinical practice to treat CDD, a condition triggered by multiple factors. However, the molecular mechanisms underlying its therapeutic effects remain poorly understood.

Hepatocellular carcinoma (HCC) is the most prevalent malignant tumor, ranking fifth in terms of fatality with poor prognosis and a low survival rate. Rhoifolin (ROF), a flavonoid constituent, has previously been shown to suppress the proliferation of breast and pancreatic cancer cells. However, its inhibitory effect on HCC has remained unexplored.
