title: N gamma-alkyl derivatives of L-glutamine as inhibitors of glutamine-utilizing enzymes.
abstract: A general, facile method to synthesize the N gamma-alkyl and N gamma,N gamma-dialkyl derivatives of L-glutamine 1a-d from L-glutamic acid as a starting substrate is presented. The obtained compounds are shown to inhibit three different glutamine-utilizing enzymes, namely: glutaminase, gamma-glutamyl transpeptidase, and glucosamine-6-phosphate synthase, with inhibitory constants within the millimolar range.
