- Capsaicin derivatives with nitrothiophene substituents: Design, synthesis and antibacterial activity against multidrug-resistant S. aureus
-
To address the emergency caused by multi-drug resistant Staphylococcus aureus, a series of novel capsaicin derivatives with nitrothiophene substituents have been designed and evaluated for the antibacterial activities against S. aureus Newman and multidrug-resistant strains (NRS-1, NRS-70, NRS-100, NRS-108, and NRS-271). The structure-activity relationship was further revealed. Compound 13c, 13f, and 13g were highly active against staphylococcal growth, with minimal inhibition concentration (MIC) values of 0.39–1.56 μg/mL. The oxadiazole-derived compound 21, a bioisostere of ester 13f, is the most potent candidate for anti-growth of five multidrug-resistant S. aureus strains with MICs of 0.20–0.78 μg/mL, which is more active compared with vancomycin in vitro. Notably, these anti-staphylococcal compounds are much less cytotoxic to the normal kidney epithelial cell line (HK293T).

- I. Discovery of a novel series of CXCR3 antagonists. Multiparametric optimization of N,N-disubstituted benzylamines
-
N,N-Disubstituted benzylamine derivatives have been identified as CXCR3 antagonists. Compounds were optimized to improve affinity and selectivity, to increase metabolic stability in human and mouse liver microsomes, to increase Caco-2 permeability. Optimization was supported by monitoring physico-chemical properties using both experimental and computational means. Several compounds with double-digit nanomolar CXCR3 affinity, favorable selectivity, microsomal stability, Caco-2 permeability and human hepatocyte clearance have been identified.

- The SAR analysis of TRPV1 agonists with the α-methylated B-region
-
A series of TRPV1 agonists with amide, reverse amide, and thiourea groups in the B-region and their corresponding α-methylated analogues were investigated. Whereas the α-methylation of the amide B-region enhanced the binding affinities and potencies as agonists, that of the reverse amide and thiourea led to a reduction in receptor affinity. The analysis indicated that proper hydrogen bonding as well as steric effects in the B-region are critical for receptor binding.

- Phenolic modification as an approach to improve the pharmacology of the 3-acyloxy-2-benzylpropyl homovanillic amides and thioureas, a promising class of vanilloid receptor agonists and analgesics
-
In order to improve the analgesic activity and pharmacokinetics of thioureas 2 and 3, which we previously developed as potent vanilloid receptor (VR) agonists, we prepared and characterized phenolic modifications of them and of their amide surro-gates (7, 8). The aminoethyl analogue of the amide template 13 was a potent analgesic with an EC50 =0.96 μg/kg in the AA-induced writhing test and with better in vivo stability than the parent phenol. Copyright
