site and displayed potent anti-vascular activity. Notably, the corresponding disodium phosphate 20b-P exhibited an excellent safety profile with the LD50 value of 599.7 mg/kg (i.v. injection), meanwhile, it significantly inhibited tumor growth and decreased microvessel density in liver cancer cell H22 allograft mouse model without obvious toxicity. Collectively, 20b and 20b-P are novel promising anti-tubulin

The synthesis and identification of sulfonamido-aryl ethers as potent bradykininB1receptorantagonists from a ∼60,000 member encoded combinatorial library are reported. Two distinct series of compounds exhibiting different structure–activity relationships were identified in a bradykininB1 whole-cell receptor-binding assay. Specific examples exhibit Ki values of ∼10 nM.
A general solid-phase synthesis of 1,2,5-trisubstituted imidazolidin-4-ones is described. The key synthetic transformation incorporates a microwave-assisted condensation of an α-amino amide on solid support with an aldehyde in solution to give the corresponding resin-bound imidazolidin-4-one in a simple one-pot procedure.

A synthesis of novel substituted 3,8,11-triazaspiro[5,6]dodecan-7-ones using a combination of solution-phase and solid-phase chemistries is described. A solution-phase approach was used to produce a key piperidine intermediate that was then incorporated into a solid-phase synthesis. The combined synthetic strategy was applied to provide a series of substituted 3,8,11-triazaspiro[5,6]dodecan-7-ones

lidin-4-one analogs, designed as hybrids of CY09 and JC121, were investigated as inhibitors of NLRP3inflammasome activation. Among them, compounds 34 and 36 were identified as promising NLRP3inhibitors by measuring the amount of active caspase-1 p20 and IL-1β produced by NLRP3inflammasome activation. Further studies indicated that both compounds inhibited NLRP3inflammasome assembly by reducing
