A new hybrid template has been designed by integrating the structural features of nimesulide and the 1,2,3-triazole moiety in a single molecular entity at the same time eliminating the problematic nitro group of nimesulide. The template has been used for the generation of a library of molecules as potential anticancer agents. A mild and greener CuAAC approach has been used to synthesize these compounds via the reaction of 4-azido derivative of nimesulide and terminal alkynes in water. Three of these compounds showed promising growth inhibition (IC ∼6-10μM) of A549, HepG2, HeLa and DU145 cancer cell lines but no significant effects on HEK293 cell line. They also inhibited PDE4B in vitro (60-70% at 10μM) that was supported by the docking studies (PLP score 87-94) in silico.

Background: Clear cell renal cell carcinoma (ccRCC) has a high incidence rate and poor prognosis, and currently lacks effective therapies. Recently, peptide-based drugs have shown promise in cancer treatment. In this research, a new endogenous peptide called CBDP1 was discovered in ccRCC and its potential anti-cancer properties were examined.

Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.

Ginseng peptides, small molecule active ingredients in ginseng, are mainly extracted naturally or synthesised chemically, but high costs and difficulties hinder further research. In this study, a ginseng hexapeptide FKEHGY, named antitumor peptide 0601 (AT0601) and its five tandem sequence repeats AT0605, were expressed in Bacillus subtilis WB600 for the first time, and the bioactivity study showed that the anticancer activity of AT0605 was even significantly higher than that of AT0601 for colon cancer CT26 cells, with IC50s of 16.82±1.
