hydantoin/necrosis

We have discovered selective and potent inhibitors of TACE that replace the common hydroxamate zinc binding group with a hydantoin, triazolone, and imidazolone heterocycle. These novel heterocyclic inhibitors of a zinc metalloprotease were designed using a pharmacophore model that we previously

A series of novel hydantoins was designed and synthesized as structural alternatives to hydroxamate inhibitors of TACE. 5-Mono- and di-substituted hydantoins exhibited activity with IC50 values of 11-60 nM against porcine TACE in vitro and excellent selectivity against other MMPs.

SCH 900567 is a specific inhibitor of tumor necrosis factor-alpha converting enzyme and is a potential candidate for the treatment of rheumatoid arthritis. [(3) H]SCH 900567 was synthesized to support the initial drug metabolism and pharmacokinetics studies. Stable isotope-labeled [(13) C3 , (15)

A number of amphiphilic and lipid-soluble drugs of heterogeneous pharmacological properties, when injected into rat anterior tibial muscles, induced acute muscle fibre necrosis. The myotoxic agents were: penicillin, cloxacillin, phenobarbital, haloperidol, diazepam, hydantoin, metoclopramide,

Nitrofurantoin was studied and evaluated because of its widespread use as a drug for treating urinary tract infections in humans, its structural relationship to known carcinogenic 5-nitrofuran compounds, and the lack of adequate studies to assess its carcinogenicity. Toxicology and carcinogenesis

Receptor-interacting protein kinases 1 and 3 (RIPK1/3) have best been described for their role in mediating a regulated form of necrosis, referred to as necroptosis. During this process, RIPK3 phosphorylates mixed lineage kinase domain-like (MLKL) to cause plasma membrane rupture. RIPK3-deficient

Necroptosis is a regulated caspase-independent cell death mechanism that can be induced in multiple cell types and is characterized by morphological features resembling necrosis. Here we describe a series of tricyclic heterocycles (i.e., 3-phenyl-3,3a,4,5-tetrahydro-2H-benz[g]indazoles,

Necrostatin-1 inhibits receptor-interacting protein (RIP)-1 kinase and programmed necrosis and is neuroprotective in adult rodent models. Owing to the prominence of necrosis and continuum cell death in neonatal hypoxia-ischemia (HI), we tested whether necrostatin was neuroprotective in the

Necroptosis is a regulated caspase-independent cell death mechanism that results in morphological features resembling necrosis. It can be induced in a FADD-deficient variant of human Jurkat T cells treated with TNF-alpha. 5-(1H-Indol-3-ylmethyl)-2-thiohydantoins and 5-(1H-indol-3-ylmethyl)hydantoins
