生物活性

MB076 is a novel heterocyclic triazole with improved plasma stability. MB076 inhibits seven different Class C Acinetobacter-derived cephalosporinases (ADCs) β-lactamase variants with Ki values < 1 μM. MB076 acts synergistically in combination with multiple cephalosporins to restore pBCSK(−) susceptibility[1].

IC50 & Target

Ki Target: ADC-7, ADC-30, ADC-162, ADC-33, ADC-219, ADC-212[1]
Ki: 0.21±0.016 μM (ADC-7), 0.058±0.005μM (ADC-30), 0.79±0.039μM (ADC-162), 0.10±0.004μM (ADC-33), 0.11±0.019 (ADC-219), 0.61±0.038μM (ADC-212)[1]

体外研究
(In Vitro)

MB076 (compound B) (0.5-5 μM, 48 h) 在人血浆中的稳定性有所提高[1]
MB076 (10 μg/mL, 48 h) 与 Ceftazidime (CAZ HY-B0593)、 Cefotaxime (CTXHY-A0088A) 联合可协同恢复 pBCSK(−) 药敏[1]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: Human Plasma
Concentration: 0.5 μM, 1 μM, 2.5 μM, 4 μM, 5 μM
Incubation Time: 48 h
Result: Showed excellent stability in human plasma, with a t1/2 value of 29 h, notably higher than the value obtained for ADC-7/S02030 (PDB4U0X) (9 h).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
