This invention provides compounds, methods, immunoassays, and kits relating to active, metabolically sensitive (“met-sensitive”) moieties of anti-HIV therapeutics, such as HIV protease inhibitors (PI) and HIV non-nucleoside reverse transcriptase inhibitors (NNRTI).
This invention relates to a method comprising reacting an amino acid derivative of the following general formula (I):
(wherein R1 represents an amino-protective group; R0 represents hydrogen or, taken together with R1, represents an amino-protecting group; R2 represents a carboxy-protecting group; X represents a leaving group) with a thiol compound of the following general formula (II):
R3SH (II)
(wherein R3 represents an alkyl group of 1 to 7 carbon atoms, an aryl group of 6 to 10 carbon atoms, or an aralkyl group of 7 to 10 carbon atoms) to give a cysteine derivative of the following general formula (III):
(wherein R0, R1, R2, and R3 are as defined above), wherein the reaction is conducted in the presence of a base and water in an organic reaction solvent.
