A β-lactamase inhibitor; inhibits Ambler class A serine penicillinases and class C cephalosporinases

Tazobactam (sodium salt) – 1 g

Brand:
Cayman
CAS:
89785-84-2
Storage:
-20
UN-No:
Non-Hazardous - /

Tazobactam is a β-lactamase inhibitor with greater activity against Ambler class A serine penicillinases and class C cephalosporinases, including TEM-1, SHV-1, and P99 (IC50s = 97, 150, and 8.5 nM) than class B metallo-β-lactamases and the class D oxacillinase OXA-1 (IC50s = 400,000 and 1,400 nM, respectively).{27901} However, it also inhibits the class D oxacillinase OXA-2 (IC50 = 10 nM). Tazobactam, in combination with piperacillin, is active against Gram-positive (MIC90s = 2-128 µg/ml) and Gram-negative bacteria (MIC90s = 4-128 µg/ml).{36746} In a neutropenic mouse model of thigh infection, tazobactam potentiates the activity of ceftolozane against Enterobacteriaceae.{36747} Formulations containing tazobactam, alone and in combination with piperacillin, have been used in the treatment of β-lacatamase-producing bacteria.

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells.

  • A small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state; activity is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM

    SC-1 – 5 mg

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal. SC-1 is a small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state.{14533} The activity of SC-1 is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM, respectively.{14533} Inhibition of RasGAP increases Ras signaling via the PI3-kinase pathway which promotes self-renewal, whereas inhibition of ERK blocks differentiation.
