摘要:The invention relates to the pure d-(17alpha)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-ene-­20-yne-3-one-3E-oxime isomer of formula (IA), the pure d-(17alpha)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-ene-20-yne-3-one-3Z-oxime isomer of formula (IB), which are of gestagen activity, as well as the process for the synthesis of the mixture of the above isomers and the pure isomers. The invention also relates to the pharmaceutical compositions - and the process for their synthesis - which contain either the pure isomer of formula (IA) or the pure isomer of formula (IB) as active ingredient as such or in combination with other active ingredients (for example an oestrogen agent) together with pharmaceutical auxiliary materials commonly used in practice.

摘要:The invention relates to a process for the synthesis of d-(17α)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-ene-20-yn-3-one-oxime (also known as norelgestromin) via acetylation of d-norgestrel at position 17; oximation of the oxo group at position 3 of the obtained d-(17α)-13-ethyl-17-(acetyloxy)-18,19-dinorpregn-4-ene-20-yn-3-one; and then hydrolyzing the acetyloxy group at position 17 of the obtained d-(17α)-13-ethyl-17-(acetyloxy)-18,19-dinorpregn-4-ene-20-yn-3-oxime derivative, thereby obtaining norelgestromin.

摘要:There is disclosed a composition comprising a water-insoluble thermoplastic compound capable of stimulating collagen synthesis (CSSC), the CSSC having a molecular weight of more than 0.6 kDa and being dispersed in a polar carrier as nano-elements having an average diameter of 200 nm or less and a viscosity of 107 mPa·s or less. The nano-elements of CSSC can be capable of stimulating the synthesis of skin proteins and/or enabling the delivery of active agents upon their application to a surface to be treated therewith. Methods for preparing the compositions and uses thereof are also provided.
