PREGABALIN ARTIFICIAL HAPTEN, ARTIFICIAL ANTIGEN AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
20220289667 · 2022-09-15 ·

Disclosed are a pregabalin artificial hapten, artificial antigen and preparation method therefor and application thereof. The structure of the pregabalin artificial hapten is shown as formula (I) and structure of the pregabalin artificial antigen is shown as formula (II). The application is in the preparation for anti-pregabalin antibodies with the pregabalin artificial antigen. The pregabalin artificial hapten retains the characteristic structure of pregabalin to the greatest extent, and has an active group that can be coupled with a carrier protein, and can be used as an antigenic determinant; the pregabalin artificial antigen obtained by further preparation can immune to obtain anti-pregabalin antibodies with high affinity, high sensitivity and strong specificity. The titer of the immune serum obtained by immunizing New Zealand white rabbits is as high as 1:90000, which can be used for rapid and accurate immunoassay of pregabalin.

Methods of Making High Enantioselective Secondary Alcohols

A new process to synthesis of compound OBI-3424 R-form and S-form products is provided. The “R-form” compound OBI-3423 was first synthesized with 48% overall yield from compound OBI-3424-5 by installation of the labile phosphate motif at later stage. The stereo chemistry is established by 5 steps chemo-enzyme combination synthesis to afford 99% optical purity. After then, the “S-form” compound OBI-3424 is prepared with improving overall yield of 54% from compound OBI-3424-5. The stereo chemistry is established by 4 steps combination of chemo-enzyme synthesis with excellent optical purity of 99%.
