  NO-Donors (VII [1]): Synthesis and Cyclooxygenase Inhibitory Properties of N-and S-Nitrooxypivaloyl-cysteine Derivatives of Naproxen — A Novel Type of NO-NSAID

  摘要：

  Nitric oxide (NO) has been reported to subserve many of the same mucosal protection mechanisms as prostaglandins and is sufficient for acute gastroprotection and ulcer healing. In fact, NO-donating NSAID hybrid compounds such as the nitrooxybutyl ester of naproxen show reduced ulcerogenic activity while maintaining anti-inflammatory activity. We introduce two prototypes of novel triple-hybrid compounds consisting of cysteine which is known to enhance the activity of organic nitrates and to reduce nitrate tolerance, an NSAID (naproxen), and an organic nitrate (nitrooxypivaloic acid). L-Cysteine ethyl ester first was N-acylated in a CH2Cl2/H2O two-phase system using the acid chlorides of naproxen or nitrooxypivaloic acid, respectively, and sodium acetate, or alternatively using the DCC-activated nitrooxy acid in absolute CH2Cl2. The N-acylated intermediates were subsequently S-acylated using the acid chlorides or alternatively the carbonyldiimidazole (CDI)-activated acids again. The two naproxon-cysteine-nitrate hybrid prodrugs were screened in vitro for their cyclooxygenase inhibitory properties relative to naproxen. In this screening the N-nitrooxyacylcysteine derivative was found to be inactive in the concentration range of 0.1-10 mumol/L against both COX-1 and COX-2, while the S-nitrooxyacylcysteine derivative had only weak activity against COX-1.

  The disclosed invention pertains to technology of fabricating and purifying synthetic dyes and may be used in various areas of industry and national economy, particularly in fabrication of materials for polarizing coatings of various purposes. In this method of purifying polycyclic dyes, the original dye is processed at least once with concentrated hydrochloric acid in the presence of at least one nitrogen-containing organic compound, such as heterocyclic base and/or aliphatic and/or aromatic amine, and/or quaternary ammonium salt in the amount of 0.1-5% of the weight of the dye at 50-100°C with subsequent filtration. After that, the obtained press-cake is processed at least once with boiling glacial ascetic acid with subsequent hot filtration of the suspension. Obtained sediment is washed with distilled water, after which the sediment is repulped in water, filtered and dried.
