Piperacillin is a broad-spectrum β-lactam antibiotic of the penicillin class.{27901,29941} It is active against Gram-negative and Gram-positive bacteria, including Enterococcus species, E. coli, and P. mirabilis (MIC50s = 0.5-2 µg/ml) as well as gentamicin-susceptible and -resistant strains of P. aeruginosa (MIC50s = 8 and 125 µg/ml, respectively).{29941} In a mouse model of systemic infection, piperacillin is active against P. aeruginosa 46220 when used alone or in combination with tazobactam (Item No. 25679; ED50s = 1.58 and 1.34 mg/animal, respectively).{37701} In the same model, it is less active against P. aeruginosa 46220 DR-2, which contains constitutively active β-lactamase, when used alone than when used in combination with tazobactam (ED50s = >20 and 4.39 mg/animal, respectively). Formulations containing piperacillin in combination with tazobactam have been used in the treatment of moderate-to-severe bacterial infections.

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 10 µg

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.

    CAY10512 – 100 mg

    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. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
