The present invention relates generally to ophthamological drugs. More specifically, the inventon relates to a method of modifying (derivatizing) ophthamological drugs so as to increase their penetration through the cornea. The invention also relates to drugs modified (derivatized) in accordance with the instant method and to the use of same in treating conditions associated with elevated intraocular pressure, particularly, glaucoma.

resource-based processes. Tungsten-based catalysts (e.g., WO3) are efficient for selectively cleaving C-C bonds of sugars to C2,3 oxygenate intermediates (e.g., glycolaldehyde) that can serve as platform molecules with high viability and versatility in the synthesis of various chemicals. Such C-Cbondcleavage follows a mechanism distinct from the classical retro-aldol condensation. Kinetic, isotope 13C-labeling
