Erlotinib mesylate Erlotinib is an EGFR inhibitor. The drug follows Iressa (gefitinib), which was the first drug of this type. Erlotinib specifically targets the epidermal growth factor receptor (EGFR) tyrosine kinase, which is highly expressed and occasionally mutated in various forms of cancer. It binds in a reversible fashion to the adenosine triphosphate (ATP) binding site of the receptor. For the signal to be transmitted, two EGFR molecules need to come together to form a homodimer. These then use the molecule of ATP to trans-phosphorylate each other on tyrosine residues, which generates phosphotyrosine residues, recruiting the phosphotyrosine-binding proteins to EGFR to assemble protein complexes that transduce signal cascades to the nucleus or activate other cellular biochemical processes. By inhibiting the ATP, formation of phosphotyrosine residues in EGFR is not possible and the signal cascades are not initiated.

ERO1 Inhibitor II, EN460 A cell-permeable thiol reactive enone (EN) compound that selectively interacts with the active-site cysteine of reduced, active form of ERO1alpha and inhibits its activity (IC50 = 1.9uM). Also prevents ERO1 re-oxidation both in vitro and in mouse embryonic fibroblasts. Activates the unfolded protein response and protects ER-stressed 293T cells. Can inhibit ERO1alpha even in the presence of an excess amount of competing thiols. Can inhibit ERO1alpha even in the presence of an excess amount of competing thiols. EN460 binding to ERO1alpha is shown to promote the loss of flavin adenine dinucleotide (FAD) from the holoenzyme.

Ertapenem Ertapenem has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of ertapenem results from the inhibition of cell wall synthesis and is mediated through ertapenem binding to penicillin binding proteins (PBPs). In Escherichia coli, it has strong affinity toward PBPs 1a, 1b, 2, 3, 4 and 5 with preference for PBPs 2 and 3. Ertapenem is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases. Ertapenem is hydrolyzed by metallo-beta-lactamases. Ertapenem has been shown to be active against most isolates of the following microorganisms in vitro and in clinical infections.
