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。

that utilize radical intermediates have been demonstrated, but only for activated alkenes, and the direct use of aqueous mineral acids remains elusive. Here we present anti-Markovnikov addition reactions of aqueous hydrochloric and nitric acid to unactivatedalkenes. The transformation is enabled by the in situ generation of photoredox-active ion pairs, derived from acridine and the mineral acid, as
