New 17 beta-estradiol (E-2) derivatives 1-11 were synthesized from an estrone derivative by addition of organometallic reagents prepared from protected alpha,omega-alkynols and further elaboration of the addition products. The estrogenic activity of these novel compounds was determined using in vitro binding competition assay and transactivation analysis. Among the E-2 derivatives synthesized, compound 2 showed the highest transactivation potency and was therefore tested for its ability to modulate cutaneous wound healing in vivo. Compound 2's ability to accelerate wound healing in ovariectomized mice and decrease the production of inflammatory molecules was comparable to that of E-2. However, the activity of compound 2 was not superimposable to E-2 with regard to the cells involved in the wound repairing process. When locally administered, compound 2 did not show any systemic activity on ER. This class of compounds with clear beneficial effects on wound healing and suitable for topical administration may lead to the generation of innovative drugs for an area of unmet clinical need.
