3α-Dimethylamino-20-(N-methylacetamido)pregn-5-ene
The title compond, C(26)H(44)N(2)O, is an steroidal alkaloid isolated from the medicinally important plant Sarcococca saligna. The mol-ecule consists of four fused rings (A-D), having chair, half-chair, chair and envelope conformations, respectively. The dimethyl-amino group is axially oriented on ring A, whereas the (N-methyl-acetamido)-ethyl group is attached equatorially on ring D. The cryst...

A method is provided for suppressing atherogenesis in which a cholesterol 20-hydroperoxide is administered, which is preferably one or both of the novel compounds: 20(R)-hydroperoxy-25-hydrocholesterol and 29(S)hydroperoxy-25-hydrocholesterol 20(R)-hydroperoxy-25 hydrocholesterol and 20(S)-hydroperoxy-25-hydrocholesterol are administered. The compositions 20(R)-hydroperoxy-25-hydrocholesterol a...
متن کامل3β-Chloro-N-methoxy-N-methylcholest-5-ene-24-carboxamide
The title compound, C26H42ClNO2, is a 3β-chloro steroid with a Weinreb amide at the C-24 position. The two cyclo-hexane and the cyclo-hexene rings adopt chair and boat conformations, respectively. The cyclo-pentane ring has an envelope conformation.
متن کامل3α-Azido-5-cholestene
The crystal structure of the title compound, C(27)H(45)N(3), has been determined as part of our investigation into the hydro-phobic modification of amino-glycoside anti-biotics. The isopropyl group showed disorder for the tertiary carbon (equal occupancies), with high thermal motion for the peripheral atoms of the isopropyl and azide groups also apparent in the structure. The axial disposition ...
متن کاملN-Carbamothioylamino-7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboximide
The title compound, C(9)H(9)N(3)O(3)S, comprises a racemic mixture of chiral mol-ecules containing four stereogenic centres. The cyclo-hexane ring tends towards a boat conformation, while the tetra-hydro-furan ring and the dihydro-furan ring adopt envelope conformations. The dihedral angle between the thio-semicarbazide fragment and the fused-ring system is 77.20 (10)°. The crystal structure is...
