标题:一种合成二甲基半胱胺盐酸盐的工艺
摘要:本发明涉及一种合成二甲基半胱胺盐酸盐的工艺,以异丁醛为起始原料,经过缩合,还原,开环再关环,开环反应制得.发明的有益效果是:通过在缩合反应中用氨水代替氨气,以及在还原反应中将硼氢化钠溶液从液面以下直接投入反应体系中,提高了反应的效率;在开环反应中保留了苯肼作为开环试剂,但将开环产品在体系中不经分离重新关环,将再关环的产品经过精馏纯化后,再在酸性条件下开环得到目标化合物,大大减少了有毒物质苯肼的残留量.

The invention also provides novel compositions comprising at least one nitric oxide donor, and, optionally, at least one therapeutic agent. The compounds and compositions of the invention can also be bound to a matrix. The invention also provides methods for treating cardiovascular diseases, for the inhibition of platelet aggregation and platelet adhesion caused by the exposure of blood to a medical device, for treating pathological conditions resulting from abnormal cell proliferation; transplantation rejections, autoimmune, inflammatory, proliferative, hyperproliferative, vascular diseases; for reducing scar tissue or for inhibiting wound contraction, particularly the prophylactic and/or therapeutic treatment of restenosis by administering the nitric oxide donor optionally in combination with at least one therapeutic agent. The invention also provides methods for treating inflammation, pain, fever, gastrointestinal disorders, respiratory disorders and sexual dysfunctions. The nitric oxide donors donate, transfer or release nitric oxide, and/or elevate endogenous levels of endothelium-derived relaxing factor, and/or stimulate endogenous synthesis of nitric oxide and/or are substrates for nitric oxide synthase and are capable of releasing nitric oxide or indirectly delivering or transferring nitric oxide to targeted sites under physiological conditions.
