The present technology is directed to prodrugs and compositions for the treatment of various diseases and/or disorders comprising methylphenidate, or methylphenidate derivatives, conjugated to at least one alcohol, amine, oxoacid, thiol, or derivatives thereof. In some embodiments, the conjugates further include at least one linker. The present technology also relates to the synthesis of methylphenidate, or methylphenidate derivatives, conjugated to at least one alcohol, amine, oxoacid, thiol, or derivatives thereof or combinations thereof.

Eleven kinds of 5-alkylamides of L-and DL-glutamic acid were synthesized and assessed for anticonvulsant effects. Against lethal convulsion induced by caffeine, maximum efficacy was observed with alkylamides possessing C7 to C8 alkyl radicals in the position 5 of glutamic acid, and the compounds having C5 to C7 alkyl groups were shown to have the highest toxity. Differences in the response between L-compound and DL-compound are not significant. Synthesized ω-alkylamides of L-glutamic acid, L-aspartic acid and DL-2-aminoadipic acid did neither increase nor decrease the oxygen consumption by the rat brain cortex slices.

A natural water soluble protocatechuic acid and L-theanine cocrystal composition is described. The cocrystal composition may be created by a method including solvent-assisted mechanical grinding. The natural water soluble cocrystal composition is suitable for sublingual administration, preferably to humans.

products were characterized by one- and two-dimensional nuclear magnetic resonance (1D and 2D NMR) and mass spectroscopy. Compounds 1-5 were then evaluated for their acetylcholinesterase (AChE) inhibitory effect (IC50 = 0.12-1.02 μM). The availability of the synthesized epicatechin derivatives 1-5 via a syntheticroute enabled the first unequivocal identification of these derivatives as tea secondary metabolites
