Synthesis of Phenylacetic Acid via Carbonylation of Benzyl Chloride in the Presence of a Water-Soluble Complex, [PdCl2{PPh2(m-C6H4SO3Na)}2], and Surfactants under Two-Phase Conditions
Convenient One-Pot Two-Step Synthesis of Symmetrical and Unsymmetrical Diacyl Ureas, Acyl Urea/Carbamate/Thiocarbamate Derivatives, and Related Compounds
chemist’s toolbox. A wide range of chemicals such as amides, hydrazides, amines, alcohols, carbazate, and sulfonate were reacted with acyl isocyanates generated by the reaction of primary amides with oxalyl chloride to give symmetrical and unsymmetrical diacyl urea derivatives, acyl ureas/carbamates/thiocarbamates, and related compounds. This method provides means for convenient one-pot, two-step synthesis

The invention comprises lipid derivatives that rapidly degrade in the pH range from 4.0 to 7.0 and lipidic delivery systems that contain them. These lipid derivatives can be used to modify the delivery properties of the lipidic delivery systems to enable prolonged circulation times or more rapid drug unloading in the target tissue. The lipid derivatives are amphipathic compounds comprising a hydrophilic head group joined to a hydrophobic group by an acid-labile ortho ester linkage. The delivery systems of the invention exhibit degradation of less than 10% within 3 hours at a pH of 7.4 and degradation greater than 50% within 60 min at a pH of 5.0.

The viral serineprotease NS2B-NS3 is one of the promising targets for drug discovery against dengue virus and other flaviviruses. The molecular recognition preferences of the protease favor basic, positively charged moieties as substrates and inhibitors, which leads to pharmacokinetic liabilities and off-target interactions with host proteases such as thrombin. We here present the results of efforts
