The disclosure provides biologically active compounds of formula (I):
and pharmaceutically acceptable salts thereof, compositions containing these compounds, and methods of using these compounds in a variety applications, such as treatment of diseases or disorders associated with E1 type activating enzymes, and with Nedd8 activating enzyme (NAE) in particular.
identification of novel S1P1 receptor agonists, the pyrazole derivative 2 emerged as a hit structure. Medicinal chemistry efforts focused not only on improving the potency of the compound but in particular also on resolving its inherent instability issue. This led to the discovery of novel bicyclo[3.1.0]hexane fused thiophene derivatives. Compounds with high affinity and selectivity for S1P1 efficiently reducing

Several novel 2,4,6-trisubstituted thieno[3,2-d]pyrimidines were synthesized from the hitherto unknown 3-amino-5-methyl-(or 5-phenyl)thiophene-2-carbonitriles 7 and 8. o-Aminonitriles 7 and 8 were obtained in a single step by conjugate addition of mercaptoacetonitrile (generated in situ) to substituted acetylenic nitriles 4 and 5 and annelation of the intermediate vinylic thioethers.
从迄今未知的3-氨基-5-甲基-(或5-苯基)噻吩-2-腈7和8合成了几种新颖的2,4,6-三取代噻吩并[3,2- d ]嘧啶。通过将巯基乙腈(原位生成)共轭添加到取代的乙炔腈4和5中,并使中间体乙烯基硫醚脱环,可以一步制得邻氨基甲酸酯7和8。
