Biological Activity

Description	Meropenem (SM 7338) is an ultra-broad spectrum injectable antibiotic.

In vitro
In vitro	Meropenem has an antibacterial spectrum which is broadly similar to that of imipenem but, whilst slightly less active against staphylococci and enterococci, it is more active against Pseudomonas aeruginosa, all Enterobacteriaceae and Haemophilus influenzae. ^[1] Meropenem is two- to four-fold more active than imipenem against Gram-negative organisms and its spectrum of antimicrobial activity is wider than those of all other drugs tested. Meropenem MICs are not significantly influenced by high inocula and the drug is generally bactericidal. Meropenem demonstrates antagonism with several other beta-lactams against strains producing Type I cephalosporinases. ^[2] Meropenem binds most strongly to penicillin-binding protein 2 of Escherichia coli and Pseudomonas aeruginosa, and to penicillin-binding proteins 1 of Staphylococcus aureus. ^[3] Meropenem is a new carbapenem antibiotic which differs chemically from imipenem/cilastatin by having a 1-beta-methyl substitution, providing it with excellent intrinsic stability to human renal dehydropeptidase-I. Meropenem has one identified metabolite, a beta-lactam ring-opened form which is devoid of microbiological activity. ^[4]

In Vivo
In vivo	Meropenem significantly increases the plamsa total clearance of valproate to about 1.5 times the control (6.09 mL/min/kg vs. 4.28 mL/min/kg) in rabbits. Meropenem significantly increases the urinary excretion of valproate- glucuronide in rabbits. ^[5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
