NO donors. Part 16: Investigations on structure–activity relationships of organic mononitrates reveal 2-nitrooxyethylammoniumnitrate as a high potent vasodilator
摘要:
The vasoactive properties of 14 organic mononitrates were investigated in vitro using PGF(2 alpha)-precontracted porcine pulmonary arteries. A surprisingly wide range of vasorelaxant potencies was observed (pD(2): 3.36-7.50). Activities showed to be highly sensitive to the molecular structure and the substituents at the molecular carrier of the nitrate group. A correlation between lipophilicity and vasorelaxant potency could not be recognized. 2-Nitrooxyethylarmmoniumnitrate (1) was found to be slightly superior to the high potency trinitrate GTN.

Aspirin prodrugs and related nitric oxide releasing compounds hold significant therapeutic promise, but they are hard to design because aspirin esterification renders its acetate group very susceptible to plasma esterase mediated hydrolysis. Isosorbide-2-aspirinate-5-salicylate is a true aspirin prodrug in human blood because it can be effectively hydrolyzed to aspirin upon interaction with plasma

The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant and or for improving ruminant animal performance by using, as active compound at least one nitrooxy alkanoic acid and/or derivative thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these compounds in feed and feed additives such as premix, concentrates and total mixed ration (TMR) or in the form of a bolus.

Pancreatic β-cell dysfunction and death are important feature of diabetes mellitus. Beta-cell protection has demonstrated clinical benefits in the treatment of this disease. In the present study, andrographolide derivatives with nitric oxide (NO)-releasing capability were synthesized and their protective effects against tert-butyl hydroperoxide (t-BHP) induced cell damage were investigated in RIN-m cells. Compound 6b was found to release a moderate amount of NO and was more potent than its natural parent andrographolide in inhibiting cell apoptosis. These findings suggested that andrographolide derivatives with NO-releasing capacity may be a potential therapy for diabetes.
胰腺β细胞功能障碍和死亡是糖尿病的重要特征。保护β细胞对治疗这种疾病有临床疗效。本研究合成了具有一氧化氮(NO)释放能力的穿心莲内酯衍生物,并研究了它们在 RIN-m 细胞中对叔丁基过氧化氢(t-BHP)诱导的细胞损伤的保护作用。研究发现,化合物 6b 能释放适量的 NO,其抑制细胞凋亡的作用比天然母体穿心莲内酯更强。这些研究结果表明,具有释放 NO 能力的穿心莲内酯衍生物可能是糖尿病的一种潜在疗法。
