  Asymmetric N-(3,3-diphenylpropyl)aminoalkyl esters of 4-aryl-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acids with antihypertensive activity

  摘要：

  A series of asymmetric 4-aryl-1,4-dihydropyridine-3,5-dicarboxylates characterized by the presence of a 3,3-diphenyl-propylamino moiety in one of the ester groups were synthesized. They exhibited remarkable antihypertensive activity in spontaneously hypertensive rats as well as affinity for the 1,4-dihydropyridines binding site labelled by H-3-nitrendipine in the calcium channel. Introduction of this bulky and lipophilic amine confers to the whole series an elevated level of antihypertensive activity and a long duration of action, a structure-dependent modulation of the activity being found only in the subset characterized by the presence of a branched propylene bridge between the ester and the amino groups. The presence of the amino group is essential for oral activity. Out of this series, compound 9u (Rec 15/2375-lercanidipine) was selected for clinical development and obtained marketing authorization as an antihypertensive in several countries.

  Inhibition of nucleoside transport By new analogues of nitrobenzylthioinosine

  摘要：

  Nitrobenzylthioinosine (NBTI, 1) was systematically modified by attachment of substituents at positions C6 and N9, and also by substitution of N1 with C. These modifications were chosen to reduce the polarity of the new compounds. Incorporation of the nitro functionality into a benzoxadiazole ring system was considered first. These new nucleosides showed high affinity (1.5-10 nM) towards the nucleoside transport protein as present on human erythrocyte ghosts. Next, modification of this benzoxadiazole ring system with C, S and O in different positions produced a number of less polar nucleosides with affinity in the higher nanomolar range. Modification of N9 was achieved with different alkyl and alcohol substituents. An n-butyl substituent proved best, although all variations yielded substantial decreases in affinity. Replacement of N1 by a carbon atom in combination with a 2-Cl substituent also resulted in a relatively potent NBTI derivative (47 nM). (C) 2003 Elsevier Science Ltd. All rights reserved.
