This invention relates to novel compounds which are antagonists or inverse agonists at one or more of the opioid receptors, to pharmaceutical compositions containing them, to processes for their preparation, and to their use in therapy.
Br/Mg-exchange reaction using reagents of the general formula R2Mg (R = sBu, Mes). Highly sensitive functional groups, such as triazene or nitro, are tolerated in these exchange reactions, enabling the synthesis of various functionalized (hetero)arene and alkene derivatives after quenching with several electrophiles including allyl bromides, acylchlorides, aldehydes, ketones, and aryl iodides.
在 –78 °C 和 25 °C 之间,通过 I/Mg 或 Br/Mg 交换反应,在甲苯中,在 10 到 120 分钟内,使用以下试剂制备各种多官能化二(杂)芳基和二烯基镁试剂通式 R2Mg (R = sBu, Mes)。在这些交换反应中可以耐受三氮烯或硝基等高度敏感的官能团,在用烯丙基溴、酰氯、醛、酮和芳基碘等多种亲电试剂淬灭后,可以合成各种功能化的(杂)芳烃和烯烃衍生物.

Substituted pyridazines having angiogenesis inhibiting activity and the generalized structural formula
wherein the ring containing A, B, D, E, and L is phenyl or a nitrogen-containing heterocycle; groups X and Y may be any of a variety of defined linking units; R1 and R2 may be defined independent substituents or together may be a ring-defining bridge; ring J may be an aryl, pyridyl, or cycloalkyl group; and G groups may be any of a variety of defined substituents. Pharmaceutical compositions containing these materials, and methods of treating a mammal having a condition characterized by abnormal angiogenesis or hyperpermiability processes using these materials are also disclosed.
A cephalosporin derivative of the formula I: ##STR1## in which X is S, O, CH.sub.2 or SO, R1 is (optionally-substituted)imidazol-2-yl or one of the C-7 acyl groups known in the cephalosporin art, R2 is hydrogen or methoxy, R3 is carboxy or a biodegradable ester thereof and --R4 is of the formula XII, XIII or XIV: ##STR2## in which R32-R40 inclusive are as defined in the specification; and the salts thereof. Pharmaceutical compositions, methods of manufacture and intermediates are also described.
