  Angiotensin-converting enzyme inhibitors. New orally active antihypertensive (mercaptoalkanoyl)- and [(acylthio)alkanoyl]glycine derivatives

  摘要：

  A variety of N-substituted (mercaptoalkanoyl)- and [(acylthio)alkanoyl]glycine derivatives was synthesized and their ability in inhibiting the activity of angiotensin-converting enzyme (ACE) was examined in vitro and in vivo. The acylthio derivatives prepared are assumed to act as prodrugs since they are much less active than the corresponding free SH compounds in vitro and can be expected to act in vivo only after conversion to the free sulfhydryl compounds. A number of these compounds are potent ACE inhibitors that lowered blood pressure in Na-deficient, conscious spontaneously hypertensive rats (SHR), a high renin model. One of the most active members of the series was (S)-N-cyclopentyl-N-[3-[(2,2-dimethyl-1-oxopropyl)thio]-2-methyl-1 -oxopropyl]glycine (REV 3659-(S), pivopril). Structure-activity relationships are discussed.

  The present invention relates to certain fluoro-amide derivatives, as described herein, which are human leukocyte elastase (HLE) inhibitors making them useful whenever such inhibition is desired, such as for research tools in pharmacological, diagnostic and related studies and in the treatment of diseases in mammals in which HLE is implicated, including treatment of tissue degenerative diseases such as pulmonary emphysema. The invention also includes intermediates useful in the synthesis of these fluoro-amide derivatives, processes for preparing them, pharmaceutical compositions containing such peptide derivatives and methods for their use.

  highly malignant tumor, and more effective treatment is urgently needed to lengthen the life of patients. In this paper a class of new 2,6,7-substituted pyrrolo[2,3-d]pyrimidine derivatives of CDK 4/6 inhibitor ribociclib (1) was designed and synthesized to investigate their effect on the proliferation of pancreatic cancer cells. The structure–activity relationship (SAR) of synthetic compounds was

  胰腺癌是高度恶性的肿瘤，迫切需要更有效的治疗以延长患者的寿命。本文设计并合成了一类新的CDK 4/6抑制剂ribociclib（1）的2,6,7-取代的吡咯并[2,3- d ]嘧啶衍生物，以研究其对胰腺癌细胞增殖的影响。基于合成化合物的体外抗增殖活性和CDK4抑制活性，分析了它们的结构活性关系（SAR）。一系列6-苯胺基羰基取代的吡咯并[2,3的d ]嘧啶衍生物（25，41 - 48）显示在MTT测定针对两种增殖癌细胞系（MIA PACA-2和BxPC-3）的显著增加的效力尽管它们的CDK4抑制活性在一个变化范围内相比均降低1。在人激酶谱分析中，最有效的化合物41被鉴定为高度选择性和有效的CDK 4/6抑制剂，它还具有良好的体外药代动力学特性，可用于进一步的体内评估。同时，有41位患者表现出与mTOR抑制剂联合治疗胰腺癌的潜力。或者，将磺酰胺片段引入吡咯并[2,3- d]嘧啶为未来优化提供新的CDK9抑制剂提供了线索。

  most active thiazines in rats, po, were 42 and 45. Of the benzothiazepines studied, 22a was the most active in inhibiting ACE in the conscious normotensive rat, ID50 = 0.15 mg/kg, po. The acute antihypertensive effects of oral administration of a number of these compounds on mean arterial pressure and heart rate were studied in spontaneously hypertensive rats (SHR) maintained on a sodium-deficient diet

  一系列1,4-噻嗪-2,5-二酮，1,4-噻嗪-2,5-二酮和1,4-苯并硫氮杂-2,5-二酮的制备及其抑菌活性检查了体内和体外的血管紧张素转换酶（ACE）。这些化合物被假定为前药，因为它们在与大鼠血浆一起温育或经0.1 N HCl水溶液或磷酸盐缓冲液（pH 7.4）处理时会发生快速的开环反应，以产生相应的无生物活性的SH化合物。噻嗪类23-25和30在向大鼠口服给药时是ACE的有效抑制剂，其效力与卡托普利（1）相当。大鼠中最活跃的噻嗪类化合物分别为42和45。在所研究的苯并硫氮平中，22a在有意识的正常血压大鼠中抑制ACE的活性最高，ID50 = 0.15 mg / kg，po。
