This invention relates to nitro compounds which show activity as histamine H2-receptor antagonists. The compounds of the invention are of Structure
where Het is an optionally substituted 5- or 6- membered fully-unsaturated heterocycle containing at least one nitrogen atom, or a furan or thiophene ring substituted by a substituted or unsubstituted aminoalkyl group; Z is sulfur, methylene or oxygen, m is 0, 1 or 2, n is 2 or 3 with m + n being 3 or 4; R3 is hydrogen or various substituents; and R" is hydrogen or lower alkyl; and acid addition salts thereof. The compounds can be prepared by condensing appropriate moieties containing the Het and pyrrole portions of the desired product. The compositions of the invention contain at least one of the compounds of the invention, and a pharmaceutical carrier.
本发明涉及具有组胺 H2 受体拮抗剂活性的硝基化合物。本发明化合物的结构如下
