Competitive Activity-Based Protein Profiling Identifies Aza-β-Lactams as a Versatile Chemotype for Serine Hydrolase Inhibition
摘要:
Serine hydrolases are one of the largest and most diverse enzyme classes in Nature. Most serine hydrolases lack selective inhibitors, which are valuable probes for assigning functions to these enzymes. We recently discovered a set of aza-beta-lactams (ABLs) that act as potent and selective inhibitors of the mammalian serine hydrolase protein-phosphatase methylesterase-1 (PME-1). The ABLs inactivate PME-1 by covalent acylation of the enzyme's serine nucleophile, suggesting that they could offer a general scaffold for serine hydrolase inhibitor discovery. Here, we have tested this hypothesis by screening ABLs more broadly against cell and tissue proteomes by competitive activity-based protein profiling (ABPP), leading to the discovery of lead inhibitors for several serine hydrolases, including the uncharacterized enzyme alpha,beta-hydrolase domain-containing 10 (ABHD10). ABPP-guided medicinal chemistry yielded a compound ABL303 that potently (IC50 approximate to 30 nM) and selectively inactivated ABHD10 in vitro and in living cells. A comparison of optimized inhibitors for PME-1 and ABHD10 indicates that modest structural changes that alter steric bulk can tailor the ABL to selectively react with distinct, distantly related serine hydrolases. Our findings, taken together, designate the ABL as a versatile reactive group for creating first-in-class serine hydrolase inhibitors.

Chiral N-heterocycliccarbenes were found to be efficient catalysts for the formal [2+2] cycloaddition reaction of alkyl(aryl)ketenes and nitroso compounds to give the corresponding 1,2-oxazetidin-3-ones in moderate to good yields with high enantioselectivities. Reductive ring-opening of the oxazetidinones give the corresponding α-hydroxy acid derivatives in good yields.

[EN] The invention encompasses novel compounds of Formula (I) or pharmaceutically acceptable salts thereof. These compounds are inhibitors of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme and are therefore useful to treat pain and/or inflammation from a variety of diseases or conditions, such as osteoarthritis, rheumatoid arthritis and acute or chronic pain. Methods of treating diseases or conditions mediated by the mPGES-1 enzyme and pharmaceutical compositions are also encompassed. [FR] L'invention porte sur de nouveaux composés de la formule (I) ou sur des sels pharmaceutiquement acceptables de ces derniers. Les composés de l'invention sont des inhibiteurs de l'enzyme prostaglandine E synthase-1 microsomale (mPGES-1) et sont par conséquent utilisés pour traiter la douleur et/ou l'inflammation provoquées par une variété d'états et de pathologies, tels que l'ostéoarthrite, l'arthrite rhumatoïde et la douleur aiguë ou chronique. L'invention se rapporte également à des procédés permettant de traiter des états ou pathologies médiés par l'enzyme mPGES-1 et à des compositions pharmaceutiques.
