Hepatocellular carcinoma (HCC) is one of the most fatal solid malignancies worldwide. Evidence suggests that thrombin stimulates tumor progression via fibrin formation and platelet activation. Meanwhile, we also found a correlation between thrombin and HCC through bioinformatics analysis.

The current global issue of antibiotic resistance is serious, and there is an urgent requirement of developing novel antibiotics. Octapeptins have recently regained interest because of their activities against resistant Gram-negative bacteria. We synthesized four natural octapeptins and 33 derivatives with diverse polarity, amphiphilicity, and acid-base properties by solid-phase synthesis and investigated their in vitro antibacterial activity and renal cytotoxicity.

Most patients with senile osteoporosis (SOP) are severely deficient in bone mass, and treatments using bone resorption inhibitors, such as bisphosphonates, have shown limited efficacy. Small-molecule osteogenesis-promoting drugs are required to improve the treatment for this disease. Previously, we demonstrated that a compound with a benzofuran-like structure promoted bone formation by upregulating BMP-2, and it exhibited a therapeutic effect in SAMP-6 mice, glucocorticoid-induced osteoporosis rats, and ovariectomized rats.

FOXM1 signalling pathways are highly expressed in multiple human cancers. Based on the crystal structure of the FOXM1 DNA binding domain, our preliminary research found ethylene glycol (4-benzyloxyphenyl) cyclopentylaminoethyl ether XST20, which could inhibit ovarian cancer cell proliferation and showed a medium affinity for the truncated protein FOXM1. This study intended to develop a FOXM1 inhibitor with stronger affinity and higher efficiency to be utilized as a molecular tool and drug candidate.

Given the importance of FOXM1 in the treatment of ovarian cancer, we aimed to identify an excellent specific inhibitor and examined its underlying therapeutic effect. The binding statistics for FDI-6 with FOXM1 were calculated through computer-aided drug design. We selected XST-119 through virtual screening, performed surface plasmon resonance and cell antiproliferative activity analysis and evaluated its antitumor efficacy in a mouse model.

The bone morphogenetic protein (BMP) pathway is a promising new target for the design of therapeutic agents for the treatment of low bone mass. This study optimized the structure of the anti-osteoporosis compound 38 by balancing its lipophilicity and improving its stability. Twenty derivatives which were not reported in the literature were designed and synthesized.
