Tryptophan 2,3-dioxygenase (TDO) is a heme-dependent enzyme that catalyzes the oxidative degradation of L-tryptophan (L-Trp) to N-formylkynurenine (NFK). A highly conserved histidine residue in the distal heme pocket has attracted great attention in the mechanistic studies of TDO. However, a

Prenucleation clusters: in situ synchrotron X-ray scattering with a one-second time resolution revealed the occurrence of nano-sized clusters during the nucleation and early growth of nanocrystals of a zeolitic imidazolate framework (ZIF). The complex crystallization process exhibits similarities with crystallization processes

A series of N-substituted acetamidines and 2-methylimidazole derivatives structurally related to W1400 were synthesized and evaluated as Nitric Oxide Synthase (NOS) inhibitors. Analogs with sterically hindering isopropyl and phenyl substituents on the benzylic carbon connecting the aromatic core of W1400
