Brief Introduction

7-amino-3-chloro-3-cephalosporin-4-carboxylic acid (7-acca) is a key intermediate for the synthesis of the second generation cephalosporin cefaclor. Cefaclor API was successfully developed in China in the 1990s, but the synthesis of API has not yet achieved large-scale industrialization. Domestic cefaclor preparations mainly rely on imported foreign APIs for sub packaging. The main reason is that the synthesis process of 7-acca is not yet mature.

Brief Introduction

M-hydroxylamine mainly acts on α Receptors, right β The effect of 1 receptor is weak; Part of the effect is by promoting the release of norepinephrine from sympathetic terminals. It is suitable for the early treatment of shock and the prevention and treatment of acute hypotension during spinal anesthesia. It can also be used for the auxiliary symptomatic treatment of hypotension caused by bleeding, drug allergy, surgical complications, brain trauma or brain tumor combined with shock, and also for the treatment of hypotension caused by cardiogenic shock or sepsis.
