摘要:
Disclosed are 1α-hydroxy-2-(3'-hydroxypropylidene)-19-nor- vitamin D compounds, pharmaceutical compositions, and methods of making and treatment thereof. The compounds are generally directed to biologically active 2-alkylidene-19-nor-vitamin D compounds and analogs thereof characterized by the presence of a 3'-hydroxypropylidene moiety at C-2 and the presence of an abbreviated alkyl side-chain free of any hydroxyl moiety.
摘要:
Compounds of formula (I) are provided where X1 and X2 are independently selected from H or hydroxy protecting groups. Such compounds may be used in preparing pharmaceutical compositions and are useful in treating a variety of biological conditions.
摘要:
Compounds of formula IA or IB are provided where X1, X2 and X3 are independently selected from H or hydroxy protecting groups and R1 is selected from straight or branched chain alkyl groups having from 1 to 8 carbon atoms; straight or branched chain alkenyl groups having from 2 to 8 carbon atoms; straight or branched chain hydroxy-substituted alkyl groups having from 1 to 8 carbon atoms; straight and branched chain hydroxy-substituted alkenyl groups having from 2 to 8 carbon atoms. Such compounds are used in preparing pharmaceutical compositions and are useful in treating a variety of biological conditions.

摘要:
This invention discloses 1 alpha -a-hydroxy-2-methylene-19-nor-pregnacalciferol and pharamaceutical uses therefor. This compound exhibits pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as an anti-cancer agent and for the treatment of skin diseases such as psoriasis as well as skin conditions such as wrinkels, slack skin, dry skin and insufficient sebum secretion. This compound also has little, if any calcemic activity and therefore may be used to treat immune disorders in humans as well as renal osteodystrophy.

摘要:
This invention discloses 2-methylene-(20R,25S)-19,27-dinor-(22E)-vitamin D analogs, and specifically 2-methylene-(20R,25S)-19,27-dinor-(22E)-lα,25-dihydroxyvitamin D3, and pharmaceutical uses therefor. This compound exhibits pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as an anti-cancer agent and for the treatment of skin diseases such as psoriasis as well as skin conditions such as wrinkles, slack skin, dry skin and insufficient sebum secretion. This compound also has little, if any, calcemic activity and therefore may be used to treat autoimmune disorders or inflammatory diseases in humans as well as renal osteodystrophy. This compound may also be used for the treatment or prevention of obesity.
