  Rational Design of Small Peptides for Optimal Inhibition of Cyclooxygenase-2: Development of a Highly Effective Anti-Inflammatory Agent

  摘要：

  Among the small peptides 2-31, (H)Gly-Gly-Phe-Leu(OMe) (30) reduced prostaglandin production of COX-2 with an IC50 of 60 nM relative to 6000 nM for COX-1. The 5 mg kg-1 dose of compound 30 rescued albino mice by 80% from capsaicin-induced paw licking and recovered it by 60% from carrageenan-induced inflammation. The mode of action of compound 30 for targeting COX-2, iNOS, and VGSC was investigated by using substance P, l-arginine, and veratrine, respectively, as biomarkers. The interactions of 30 with COX-2 were supported by isothermal calorimetry experiments showing a Ka of 6.10 +/- 1.10 X 104 M-1 and Delta G of -100.3 kJ mol-1 in comparison to a Ka 0.41 X 103 +/- 0.09 M-1 and Delta G of -19.2 +/- 0.06 kJ mol(-1) for COX-1. Moreover, compound 30 did not show toxicity up to a 2000 mg kg(-1) dose. Hence, we suggest peptide 30 as a highly potent and promising candidate for further development into an anti-inflammatory drug.

  The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalyzed kinetically controlled peptide synthesis was demonstrated in several segment condensations carried out in organic media with low water content. Then this approach was successfully applied to the construction of the Leuenkephalin sequence via the 4 + 1 segment condensation.

  The coupling efficiency in alpha-chymotrypsin-catalysed peptide synthesis is greatly improved by the use of activated esters such as the 2,2,2-trifluoroethyl ester as acyl donor instead of the conventional methyl ester; this approach Is useful for the incorporation of non-protein amino acids into peptides.
