Identification of 2-PMPA as a novel inhibitor of cytosolic carboxypeptidases
Biochem Biophys Res Commun 2020 Dec 17;533(4):1393-1399.PMID:33092792DOI:10.1016/j.bbrc.2020.10.029.
Cytosolic carboxypeptidases (CCPs) comprise a unique subfamily of M14 carboxypeptidases and are erasers of the reversible protein posttranslational modification- polyglutamylation. Potent inhibitors for CCPs may serve as leading compounds targeting imbalanced polyglutamylation. However, no efficient CCP inhibitor has yet been reported. Here, we showed that 2-phosphonomethylpentanedioic acid (2-PMPA), a potent inhibitor of the distant M28 family member glutamate carboxypeptidase II (GCPII), rather than the typical M14 inhibitor 2-Benzylsuccinic acid, could efficiently inhibit CCP activities. 2-PMPA inhibited the recombinant Nna1 (a.k.a. CCP1) for hydrolyzing a synthetic peptide in a mixed manner, with Ki and Ki' being 0.11 μM and 0.24 μM respectively. It inhibited Nna1 for deglutamylating tubulin, the best-known polyglutamylated protein, with an IC50 of 0.21 mM. Homology modeling predicted that the R-form of 2-PMPA is more favorable to bind Nna1, unlike that GCPII prefers to S-form. This work for the first time identified a potent inhibitor for CCP family.
Mechanistic insight into the inactivation of carboxypeptidase A by alpha-benzyl-2-oxo-1,3-oxazolidine-4-acetic acid, a novel type of irreversible inhibitor for carboxypeptidase A with no stereospecificity
J Org Chem 2001 Sep 21;66(19):6462-71.PMID:11559199DOI:10.1021/jo010421e.
On the basis of the active site topology and enzymic catalytic mechanism of carboxypeptidase A (CPA), a prototypical zinc-containing proteolytic enzyme, alpha-benzyl-2-oxo-1,3-oxazolidine-4-acetic acid (1), was designed as a novel type of mechanism-based inactivator of the enzyme. All four possible stereoisomers of the inhibitor were synthesized in an enantiomerically pure form starting with optically active aspartic acid, and their CPA inhibitory activities were evaluated to find that surprisingly all of the four stereoisomers inhibit CPA in a time dependent manner. The inhibited enzyme did not regain its enzymic activity upon dialysis. The inactivations were prevented by 2-Benzylsuccinic acid, a competitive inhibitor that is known to bind the active site of the enzyme. These kinetic results strongly support that the inactivators attach covalently to the enzyme at the active site. The analysis of ESI mass spectral data of the inactivated CPA ascertained the conclusion from the kinetic results. The values of second-order inhibitory rate constants (k(obs)/[I](o)) fall in the range of 1.7-3.6 M(-1) min(-1). The lack of stereospecificity shown in the inactivation led us to propose that the ring cleavage occurs by the nucleophilic attack at the 2-position rather than at the 5-position and the ring opening takes place in an addition-elimination mechanism. The tetrahedral transition state that would be generated in this pathway is thought to be stabilized by the active site zinc ion, which was supported by the PM3 semiemprical calculations. In addition, alpha-benzyl-2-oxo-1,3-oxazolidine-5-acetic acid (18), a structural isomer of 1 was also found to inactivate CPA in an irreversible manner, reinforcing the nucleophilic addition-elimination mechanism. The present study demonstrates that the transition state for the inactivation pathway plays a critical role in determining stereochemistry of the inactivation.
Benzyl radical addition reaction through the homolytic cleavage of a benzylic C-H bond
Org Biomol Chem 2011 Apr 7;9(7):2062-4.PMID:21331427DOI:10.1039/c0ob01148g.
Direct generation of a benzyl radical by C-H bond activation of toluenes and the addition reaction of the resulting radical to an electron deficient olefin were developed. The reaction of dimethyl fumarate with toluene in the presence of Et(3)B as a radical initiator at reflux afforded 2-Benzylsuccinic acid dimethyl ester in good yield.
