  Design, Synthesis, and Pharmacological Evaluation of Bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl Sulfide 3 (BPTES) Analogs as Glutaminase Inhibitors

  摘要：

  Bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide (BPTES) is a potent and selective allosteric inhibitor of kidney-type glutaminase (GLS) that has served as a molecular probe to determine the therapeutic potential of GLS inhibition. In an attempt to identify more potent GLS inhibitors with improved drug-like molecular properties, a series of BPTES analogs were synthesized and evaluated. Our structure activity relationship (SAR) studies revealed that some truncated analogs retained the potency of BPTES, presenting an opportunity to improve its aqueous solubility. One of the analogs, N-(5-{2-[2-(5-amino-[1,3,4]thiadiazol-2-yl)-ethylsulfanyl]-ethyl}-[1,3,4]thiadiazol-2-yl)-2-phenylacetamide 6, exhibited similar potency and better solubility relative to BPTES and attenuated the growth of P493 human lymphoma B cells in vitro as well as in a mouse xenograft model.

  A series of allosteric kidney-type glutaminase (GLS) inhibitors were designed and synthesized using 1,4-di(5-amino-1,3,4-thiadiazol-2-yl)-butane as a core scaffold. A variety of modified phenylacetyl groups were incorporated into the 5-amino group of the two thiadiazole rings in an attempt to facilitate additional binding interactions with the allosteric binding site of GLS. Among the newly synthesized compounds, 4-hydroxy-N-[5-[4-[5-[(2-phenylacetypamino]-1,3,4-thiadiazol-2-yl]butyl]-1,3,4-thiadiazol-2-yl]-benze-neacetamide, 2m, potently inhibited GLS with an IC50 value of 70 nM, although it did not exhibit time-dependency as seen with CB-839. Antiproliferative effects of 2m on human breast cancer lines will be also presented in comparison with those observed with CB-839.
