  Inhibition of the mammalian .beta.-lactamase renal dipeptidase (dehydropeptidase-I) by Z-2-(acylamino)-3-substituted-propenoic acids

  摘要：

  The title enzyme deactivates the potent carbapenem antibiotic imipenem in the kidney, producing low antibiotic levels in the urinary tract. A series of (Z)-2-(acylamino)-3-substituted-propenoic acids (3) are specific, competitive inhibitors of the enzyme capable of increasing the urinary concentration of imipenem in vivo. Many of the compounds were prepared in one step from an alpha-keto acid and a primary amide. The optimum R2 groups are 2,2-dimethyl, -dichloro, and -dibromocyclopropyl. With R2 = 2,2-dimethylcyclopropyl (DMCP), a wide variety of R3 groups including alkyl, oxa- and thiaalkyl, and alkyl groups containing acidic, basic, and neutral substituents give effective inhibitors with Ki values of 0.02-1 microM and a range of pharmacokinetic properties. By resolution of enantiomers and X-ray crystallography, the enzyme-inhibitory activity of the DMCP group was found to reside with the 1S isomer. The cysteinyl compound 176 (cilastatin, MK-0791) has the desired pharmacological properties and has been chosen for combination with imipenem.

  Novel compounds of the general formula wherein R2 is 2,2-dimethylcyclopropyl or 2,2-dichlorocyclopropyl; R1 is hydrogen, loweralkyl of 1-6 carbon atoms, dialkylaminoalkyl, or a pharmaceutically acceptable cation; R3 is a hydrocarbon chain of 3-7 carbon atoms, optionally having a terminal substituent which is trimethylammonium, amidino, guanidino, 2-amino-2-carboxyethyl- thio, or ureido, which selectively inhibit the metabolism of dipeptidase (E.C.3.4.13.11) and therefore are useful in combination with antibacterial products by preference with the thienamycin class of compounds.

  通式中 R2 为 2,2-二甲基环丙基或 2,2-二氯环丙基；R1 为氢、1-6 个碳原子的低级烷基、二烷基氨基烷基或药学上可接受的阳离子；R3 为 3-7 个碳原子的烃链，任选具有一个末端取代基，该取代基为三甲基铵、脒基、胍基、2-氨基-2-羧乙基硫代或脲基，可选择性地抑制二肽酶（E.C.3.4.13.11）的代谢，因此可优先与噻吩霉素类化合物结合使用。
