Abstract: Dental materials and associated methods are described based on multicyclic allyl sulphides with general Formula (I): in which R1 is H or a C1-C10 alkyl radical; R2 is H or a C1-C10 alkyl radical; R3 is absent or is a C1-C20 alkylene radical which can be interrupted by O or S, a cycloaliphatic C4-C12 radical, a bicyclic C6-C12 radical, a C6-C14 arylene or C7-C20 alkylene arylene radical; R4 is an n-times substituted aliphatic C2 to C20 hydrocarbon radical which can be interrupted by O or S, a cycloaliphatic C4-C12 radical, an aromatic C6-C14 radical, an aliphatic-aromatic C7-C20 radical or a heterocyclic radical which can contain 4 to 20 carbon atoms and 1 to 6 heteroatoms which are selected from N, O, P and/or S atoms, or which is formed exclusively by these heteroatoms; R5 is absent or is a C1-C10 alkylene radical; X is absent or is O, S, —O—CO— or —O—CO—NH—; Y is absent or is O, S, —O—CO— or —O—CO—NH—; m is 0 or 1 and n is an integer from 3 to 6.

Abstract: The present invention is related to novel 21-hydroxy-6,19-oxidoprogesterone (21OH-6OP) analogues, their use as antiglucocorticoids for the treatment and/or prophylaxis of diseases associated to an excess of glucocorticoids. In particular, the invention relates to the use of novel 21-hydroxy-6,19-oxidoprogesterone (21OH-6OP) analogues having the formula FORMULAwherein X is S, SO and SO2, and R is either M or OH, for treating Cushing's syndrome, iatrogenic hypercortisolism or depression. Also the present invention is related to methods of preparing the novel 21-hydroxy-6,19-oxidoprogesterone (21OH-6OP) analogues.
