The invention relates to solid supports useful in medical applications that provide controlled release of drugs, such as peptides, nucleic acids and small molecules. The drugs are covalently coupled to the solid support through a linkage that releases the drug or a prodrug through controlled beta elimination.

heterologously expressed GABA A alpha ibeta 3gamma 2 receptors (i = 1-6). The effects of 5-aminomethyl-3 H-[1,3,4]oxadiazol-2-one 5d were comparable to GABA for all alpha subunit isoforms. 5-piperidin-4-yl-3 H-[1,3,4]oxadiazol-2-one 5a and 5-piperidin-4-yl-3 H-[1,3,4]oxadiazol-2-thione 6a were weak agonists at alpha 2-, alpha 3-, and alpha 5-containing receptors. When coapplied with GABA, they were antagonistic
against multi-drug resistant bacteria, is developed. Compared with the original syntheticroute, this new approach is two steps shorter, and all of the steps involve simple purifications without column chromatography. More importantly, it avoids the use of explosive azide compounds and expensive metal catalysts. The newreaction conditions are mild and safe, which is more suitable for the scalable synthesis
