Thromboxane receptor antagonism combined with thromboxane synthase inhibition. 4. 8-[[(4-Chlorophenyl)sulfonyl]amino]-4-[3-(3-pyridinyl)propyl]octanoic acid and analogs
摘要:
The title compound (10a) and its analogs were synthesized and found to possess two activities, the inhibition of the biosynthesis of thromboxane A2 and antagonism of its receptors. The in vitro and in vivo profile of these compounds as thromboxane receptor antagonists (TxRAs) and thromboxane synthase inhibitors (TxSIs) is described. 10a and its analogs displayed very potent TxRA activity in human washed platelets (IC50 almost-equal-to 10(-7)-10(-9) M) and dog saphenous vein (pA2 almost-equal-to 9) and also potent TxSI activity (IC50 almost-equal-to 10(-9) M). The good bioavailability and the long duration of action of some of these compounds was demonstrated using ex vivo measurement of the TxRA activity upon oral administration to guinea pigs. Compounds 10a, 20, and 33 potently inhibited arachidonic acid induced bronchoconstriction in guinea pigs.

pharmaceutical, and agrochemical compounds. Access to such scaffolds has been the subject of long-standing synthetic interest. Herein, we report the synthesis of such scaffolds via a palladium-catalyzedC(sp3)–C(sp3) coupling between (chloromethyl)aryls and air-/moisture-stable N,N-dialkylaminomethyltrifluoroborate salts. Rapid hit identification was achieved using microscale high-throughput experimentation
