Improved delivery through biological membranes. 26. Design, synthesis, and pharmacological activity of a novel chemical delivery system for. beta.-adrenergic …
Novel ketoxime analogues of known@-blockers (propranolol, timolol, carteolol) were synthesized and tested as potential site-specific chemical delivery systems. It was assumed that a hydrolysis-reduction sequence could produce the active@-blockers in the iris-ciliary body. It was found that some of these bioprecursors are remarkably active in reducing intraocular pressure in rabbits. The ketoxime derivative of propranolol is more effective ...
