Structure-activity relationships among di- and tetramine disulfides related to benextramine
摘要:
The synthesis and irreversible alpha-blocking activity in the rat vas deferens of a series of tetra- and diamine disulfides 2-38, structural analogues of benextramine (BHC), are described. All compounds containing a central cystamine moiety displayed an irreversible alpha-adrenergic blockade at concentrations ranging from 10(-4) to 6 X 10(-6)M. Potency was increased in cystamines N,N'-disubstituted with 6-aminohexyl groups, especially when the outer nitrogen atoms bear arylalkyl substituents or are enclosed in a ring. However, N,N,N',N'-tetrasubstituted cystamines were poor blockers. Structural specificity in the outer portion of the tetramine disulfide is low, since many types of substituents gave rise to potent alpha-blockers. Even replacement of the outer amines with nonbasic ethers or amides was observed to maintain irreversible alpha-blockade.

The C(sp3)–C(sp3) cross-coupling of alkyl halides with alkyl tosylates has been developed by employing a combination of nickel and nucleophilic cobalt catalysts in the presence of a manganese reductant. This method provides a straightforward route to a diverse set of not only secondary–primary but also primary–primary C(sp3)–C(sp3) linkages under mild conditions without using alkyl-metallic reagents
The use of substituted amides for modulating the activity of 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) and the use of these compounds as pharmaceutical compositions, are described. Also a novel class of substituted amides, their use in therapy, pharmaceutical compositions comprising the compounds, as well as their use in the manufacture of medicaments are described. The present compounds are modulators and more specifically inhibitors of the activity of 11βHSD1 and may be useful in the treatment, prevention and/or prophylaxis of a range of medical disorders where a decreased intracellular concentration of active glucocorticoid is desirable.
