Discovery and optimization of a series of small-molecule allosteric inhibitors of MALT1 protease.

We describe a series of potent and highly selective small-molecule MALT1 inhibitors, optimized from a High-Throughput Screening hit. Advanced analogues such as compound 40 show high potency (IC: 0.01 µM) in a biochemical assay measuring MALT1 enzymatic activity, as well as in cellular assays: Jurkat T cell activation (0.

Design and synthesis of a series of bioavailable fatty acid synthase (FASN) KR domain inhibitors for cancer therapy.

We designed and synthesized a new series of fatty acid synthase (FASN) inhibitors with potential utility for the treatment of cancer. Extensive SAR studies led to highly active FASN inhibitors with good cellular activity and oral bioavailability, exemplified by compound 34. Compound 34 is a potent inhibitor of human FASN (IC = 28 nM) that effectively inhibits proliferation of A2780 ovarian cells (IC = 13 nM) in lipid-reduced serum (LRS).

Survival in experimental Candida albicans infections depends on inoculum growth conditions as well as animal host.

Evidence is presented that the growth medium used to prepare a Candida albicans challenge inoculum is a significant factor determining the ability of a fungus strain to gain an initial invasive hold immediately after injection into an animal host, and thus determining gross strain lethality. Three C. albicans strains, one known to be attenuated in virulence, were grown in two broth media and injected intravenously at different doses into female NMRI mice and male albino guinea pigs.
