Cyclometallated π-allyliridium C,O-benzoates modified with (S)-tol-BINAP, which are stable to air, water, and SiO , catalyze highly enantioselective N-allylations of indoles and related azoles. This reaction complements previously reported metal-catalyzed indole allylations in that complete levels of N versus C3 and branched versus linear regioselectivity are observed.

Inhibition of RIPK1-driven necroptosis ameliorates inflammatory hyperalgesia caused by lipopolysaccharide: involvement of TLR-, NLRP3-, and caspase-11-mediated signaling pathways.

Increasing evidence suggests that inhibition of receptor-interacting serine/threonine-protein kinase (RIPK) 1/RIPK3/mixed lineage kinase domain-like pseudokinase (MLKL) necrosome has protective effects in vivo models of painful conditions seen in humans associated with inflammation and demyelination in the central nervous system. However, the contribution of RIPK1-driven necroptosis to inflammatory pain remains unknown. Therefore, this study aims to determine the effect of necrostatin (Nec) -1s, a selective RIPK1 inhibitor, on lipopolysaccharide (LPS)-induced inflammatory pain and related underlying mechanisms.

A new series of 13 ritonavir-like inhibitors of human drug-metabolizing CYP3A4 was rationally designed to study the R side-group and R end-group interplay when the R side-group is represented by phenyl. Spectral, functional, and structural characterization showed no improvement in the binding affinity and inhibitory potency of R/R-phenyl inhibitors upon elongation and/or fluorination of R-Boc (tert-butyloxycarbonyl) or its replacement with benzenesulfonyl. When R is pyridine, the impact of R-phenyl-to-indole/naphthalene substitution was multidirectional and highly dependent on side-group stereo configuration.

Clear cell renal cell carcinoma (ccRCC) is one of the most common and aggressive malignancies of the urinary system. Despite being the first-line treatment for advanced ccRCC, vascular endothelial growth factor receptor inhibitors (VEGFRis) face significant limitations due to both initial and acquired resistance, which impede complete tumor eradication. Using a CRISPR/Cas9 library screening approach, was identified as a resistance-associated gene for three prevalent VEGFRis (Sunitinib, Axitinib, and Sorafenib).
