  名称：

  Regioselective O-alkylation of cortienic acid and synthesis of a new class of glucocorticoids containing a 17α-alkoxy, a 17α-(1′-alkoxyethyloxy), a 17α-alkoxymethyloxy, or a 17α-methylthiomethyloxy function

  摘要：

  The synthesis of a new class of glucocorticoids, to be evaluated as anti-inflammatory agents with expected low systemic toxicity, is described. The new steroids possess a 17-beta-chloromethyl carboxylate function and a 17-alpha-alkoxy, a 17-alpha-(1'-alkoxyethyloxy), a 17-alpha-alkoxymethyloxy, or a 17-alpha-methylthiomethyloxy function. A 17-alpha-alkoxy function is a new feature in cortisol analogs.

  Methods and compositions for enhancing the activity and/or duration of action of soft anti-inflammatory steroids of the haloalkyl 17α-alkoxy-11β-hydroxyandrost-4-en-3-one-17β-carboxylate type and the corresponding Δ 1,4 compounds and of anti-inflammatory steroids of the hydrocortisone and prednisolone type are described. The enhancing agents have the formula: wherein R is H or C 1 -C 4 alkyl; Z 1 is carbonyl or β-hydroxymethylene; X 1 is —O— or —S—; R 5 is —OH, —OR 6 , —OCOOR 6 or —OCOR 7 wherein R 6 is C 1 -C 4 alkyl and R 7 is C 1 -C 4 alkyl, fluoromethyl or chloromethyl; and the dotted line in ring A indicates that the 1,2-linkage is saturated or unsaturated; with the proviso that when R is C 1 -C 4 alkyl, then R 5 is —OH.
