Acyl sulfonamide, peri-substituted, fused bicyclic ring compounds useful for the treatment or prophylaxis of a prostaglandin-mediated disease or condition are disclosed. The compounds are of the general formula
A representative example is:
The present application relates to novel 1-phenyl-1H-imidazo[1,2-b]pyrazole derivatives, to processes for their preparation, to their use for the treatment and/or prevention of diseases and to their use for preparing medicaments for the treatment and/or prevention of diseases, in particular angiogenic disorders and hyperproliferative disorders, where neovascularization plays a role, such as, for example, neoplastic disorders and tumour disorders. Such treatments can be carried out as monotherapy or else in combination with other medicaments or further therapeutic measures.
like hydroxylamines and acyl or sulfonyl hydrazides led to the corresponding imine derivatives of the aldehyde. Hydrazine, alkyl and aryl hydrazines react with madurahydroxylactone under cyclization to give compounds of the new heterocyclic basic structure naphthaceno[1,2-g]phthalazine. Some new compounds strongly inhibit gram-positive bacteria, in part stronger than the parent compound.

Compositions for the oxidative dyeing of keratin fibers, comprising a medium suitable for dyeing and at least one bicyclic fused 5-5-membered aza heteroaromatic keratin dyeing compounds having a ring junction nitrogen and an N-hydroxy or N-amino group and derivatives thereof. A method for oxidative dyeing of keratin fibers, comprising applying such compositions in the presence of an oxidizing agent, for a period sufficient to develop the desired coloration.
Abstract A new hydrazone of gossypol with 2,2′-diethoxyethyl hydrazine (GHOE) has been synthesised and its structure has been studied by FT-IR, 1H NMR, 13CNMR as well as PM5 semiempirical methods. All the studies provide clear evidence of the existence of the GHOE in the solution in the N-imine–N-imine tautomeric form. The structure and the spectroscopic behaviour of this tautomer are discussed in
