摘要:
Compounds of Formula I, wherein Y1, Y2, R1-R6, Q and Z are as defined herein, are vitamin D derivatives. These compounds are useful for, e.g., the treatment hyperprolifierative diseases of the skin, tumor diseases and precancerous stages, auto-immune diseases, rejection reactions in the case of autologous, allogenic or xenogenic transplants, AIDS, atopic skin conditions, secondary hyperparathyroidism, renal osteodystrophia, senile and postmenopausal osteoporosis, diabetes mellitus type II, degenerative diseases of the peripheral and central nervous system, hypercalcemias, granulomatous diseases, paraneoplastic hypercalcemias, hypercalcemias in hyperparathyroidism, hirsutism, ateriosclerosis, and/or inflammatory diseases.

摘要:
The invention discloses side-chain homologous vitamin D derivatives of formula I ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, B, and D have the meanings defined in the specification and either (1) A is a direct bond between carbon atoms 20 and 22 and X is an oxy alkylene radical, --(CH.sub.2).sub.n O-- where n is 1 to 3; (2) A is a methylene bridge, --CH.sub.2 --, between carbon atoms 20 and 22 and X is either an alkylene radical, --(CH.sub.2).sub.n -- or an oxy alkylene radical, --(CH.sub.2).sub.n O--, where n is 1 to 3; or (3) if A is a direct bond and B and D together form a second bond, then X(R.sup.5) (R.sup.6) is ##STR2## The compounds possess proliferation-inhibiting and cell-differentiating activity.
摘要:
The invention relates to vitamin D derivatives, modified in 20-position, of general formula I ##STR1## in which X, Y, Z, R.sub.1, R.sub.2 as well as R.sub.3 have the meaning indicated in the description, process for their production and their use as agents for treatment of hyperproliferative diseases of the skin.
摘要:
New 20-methyl-substituted vitamin D derivatives of general formula I ##STR1## are described in whichR.sup.1 means a hydrogen atom, a hydroxy group or an alkanoyloxy group with 1 to 12 carbon atoms or a benzoyloxy group,R.sup.2 means a hydrogen atom or an alkanoyl group with 1 to 12 carbon atoms or a benzoyl group andR.sup.3 means a saturated or unsaturated, straight-chain or branched hydrocarbon radical with up to 18 C atoms, which optionally contains carbocyclic structures, optionally substituted with one or more hydroxy, oxo, amino group(s) and/or one or more halogen atom(s) as well as optionally exhibits one or more oxygen, sulfur and/or nitrogen atom(s) as a bridging link or links in the hydrocarbon radical, and a process for their production.Relative to calcitriol, the new compounds exhibit a greatly improved induction of cell differentiation (HL-60) and are suitable for the production of pharmaceutical agents.
摘要:
Nitroimidazoles of the formula ##STR1## wherein R is dialkylaminoacryloyl; 3-, 4-, or 5-pyrazolyl or a mixture thereof which is unsubstituted or substituted by alkyl or, at the 1-position, by hydroxyalkyl or a nitro ester thereof, acyloxyalkyl, nitro, phenyl or phenyl p-substituted by halo, alkoxy or nitro, or, in the 3- or 5-position or a mixture thereof by nitro; 3- or 5-alkyl-4-isooxazolyl or a mixture thereof; or 4-alkyl-5-pyrimidinyl, unsubstituted or substituted by alkyl, amino, 2-furyl or 5-nitro-2-furyl, and the physiologically acceptable acid addition salts thereof, possess anti-protozoal activity, e.g., against trichomonas vaginalis and Entamoeba histolytica.
