  • Patent number: 5116829
    Abstract: A 21-substituted steroid compound is disclosed. The compound has a structure of formula (I), ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl, lower alkenyl, lower alkoxy, or phenyl group, R.sup.2 is a hydroxyl group or an acyloxy group having 1-6 carbon atoms, R.sup.3 is a hydrogen atom or a lower alkyl group, or R.sup.2 and R.sup.3 may together form a lower alkylidenedioxy group, X.sup.1 and X.sup.2 may be the same or different and individually represents a hydrogen atom or a halogen atom, Y.sup.1 and Y.sup.2 may be the same or different and individually represents a methylene group or a sulfur atom, Z is a sulfur atom or an imino group, the wave line means that the configuration of R.sup.3 may be of either .alpha. or .beta., and dotted line between the 1 and 2 position means that the bond may be the double bond.

  • Patent number: 4879274
    Abstract: Novel external medications comprise, as essential components, the following three components (A) to (C):(A) an .alpha.-monoglyceryl ether represented by the following formula (I): ##STR1## wherein R means an alkyl or alkenyl group having 10 - 24 carbon atoms; (B) a physiologically active material; and(C) an oily material.The external medications have extremely high skin occlusive properties and significantly-improved absorptivity of phosiologically active materials. Therefore, a smaller amount of the medications compared with the conventional ones can give sufficient pharmacological effects and thus side effects can be reduced. The external medications may contain physiologically active materials such as drugs, growth hormones and the like, which are expected to show pharmacological effects upon their percutaneous absorption.
