Biapenem (also called L-627, CLI 86815, LJC10627) is a potent carbapenem antibiotic with activity against both Gram-positive and Gram-negative bacterial strains. Biapenem has activity comparable to those of Imipenem and Meropenem against all groups of anaerobes with MICs for 90% of the strains tested of 0.06 to 2 mg/mL. Biapenem is more active than ampicillin-sulbactam, ticarcillin-clavulanate, piperacillin, cefoxitin, cefotaxime, and ceftriaxone. Biapenem is also active against all of the B. capillosus, Prevotella, Clostridium, and Eubacterium strains and anaerobic cocci tested. Biapenem shows broad antibacterial activity against both Gram-positive and Gram-negative clinical isolates.

Biapenem shows broad antibacterial activity against both Gram-positive and Gram-negative clinical isolates. Biapenem is found to be approximately as active as imipenem, inhibiting 90% of isolates of most species at concentrations within one dilution of the MIC of imipenem for 90% of the isolates.

| Solubility (In Vivo) |
Solubility in Formulation 1: 11.11 mg/mL (31.71 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication (<60°C).
Solubility in Formulation 2: PBS: 11.11 mg/mL (31.71 mM) (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
