Dirithromycin is the second-generation erythromycin macrocyclic (fourteen member ring) lactone antibiotics; made from the condensation reaction between 2-methoxyethoxy acetaldehy de and erythromycylamine. It has similar structure to erythromycin. It can subject to in vivo non-enzymatic hydrolysis into erythromycin cyclic amines. It takes effect through targeting the 50S ribosomal subunit of sensitive pathogenic microorganisms, blocking the bacterial peptide bond formation, which further inhibits protein synthesis to play antibacterial activity.

Function and Application of Dirithromycin CAS 62013-04-1

1. Dirithromycin is a macrolide antibiotic pro-drug of 9S-erythromycylamine, a close analogue of erythromycin in which the 9-keto group is replaced with an amino group in the S-configuration. Although erythromycylamine overcomes the acid instability of erythromycin, it is poorly absorbed following oral administration. Dirithromycin is formed by reacting erythromycylamine with an aldehyde to form a Schiff base which undergoes cyclisation to an oxazine with the C11-alcohol. Dirithromycin provides higher tissue levels and prolonged in vivo half-life by slowly releasing erythromycylamine.
2. Dipyridamole prevents platelets sticking to the replacement heart valve and causing a blood clot on the valve. It is used to dilate blood vessels in people with peripheral arterial disease and coronary artery disease. This compound has been shown to suppress high glucose-induced osteopontin mRNA expression and protein secretion, as well as inhibit cAMP and cGMP hydrolysis. Research indicates that Dipyridamole is a non-specific nucleoside transport inhibitor with the ability to increase the effects of adenosine in sinoatrial and atrioventricular nodes. Dipyridamole is an inhibitor of ENT1 and ENT2.
3. Dipyridamole is a selective inhibitor of phosphodiesterase V (PDE 5); potent coronary vasodilator drug; adenosine transport inhibitor; inhibitor of platelet aggregation
