pyrrolidinone

Ceftobiprole medocaril (BAL5788), the parenteral prodrug of Ceftobiprole, is a broad-spectrum cephalosporin effective against Methicillin-resistant Staphylococcus aureus (MRSA).

5-Hydroxy-2-pyrrolidinone is a natural product of Buddleja, Loganiaceae. The catalog number is TN3117 and the CAS number is 62312-55-4. 5-Hydroxy-2-pyrrolidinone can be used as a reference standard.

Raltegravir (MK-0518) is a pyrrolidinone derivative and HIV INTEGRASE INHIBITOR that is used in combination with other ANTI-HIV AGENTS for the treatment of HIV INFECTION.

N-Methylpyrrolidone (1-Methyl-2-pyrrolidinone) is a five-membered cyclic amide and a widely used industrial organic polar solvent in the manufacture of adhesives, paints, fuels, and pharmaceuticals.

Felipyrine is a derivative of 1-aryl-2-pyrrolidinone, known for its anti-inflammatory properties.

The prostaglandin E receptor 4 (EP4) is one of four G protein-coupled receptors that mediate the actions of prostaglandin E2 . Binding of PGE2 to the EP4 receptor causes an increase in intracellular cyclic AMP, which plays important roles in bone formation and resorption, cancer, and atherosclerosis. KMN-80 is a substituted γ-lactam (pyrrolidinone) derivative of PGE1 that acts as a selective and potent agonist of EP4 with an IC50 value of 3 nM (IC50 = 1.4 μM for EP3 and > 10 μM for all other prostanoid receptors). In functional assays it has been shown to stimulate secreted alkaline phosphatase gene reporter activity in EP4-transfected HEK293 cells with an EC50 value of 0.19 nM, demonstrating >5,000 and 50,000-fold selectivity against EP2 and TP, respectively. KMN-80 can induce the differentiation of bone marrow stem cells from both young and aged rats into osteoblasts in vitro (EC50s = 20 and 153 nM, respectively) and exhibits favorable tolerability up to at least 10 μM, whereas the EP4 agonist L-902,688 is highly cytotoxic at similar concentrations in these cells. KMN-80 has been used to repair calvarial defects in an in vivo rat craniomaxillofacial reconstruction model (rate of reduction in defect size equivalent to BMP-2 treated rats) and to promote bone formation in a rat incisor tooth socket model.

(R)-(+)-Blebbistatin O-Benzoate is a derivative of Blebbistatin. (R)-(+)-Blebbistatin is a 1-phenyl-2-pyrrolidinone derivative and a selective inhibitor of non-muscle myosin II. It blocks cell blebbing rapidly and reversibly and also disrupts directed cell migration and cytokinesis in vertebrate cell. (R)-(+)-Blebbistatin can also inhibit contraction of the cleavage furrow without disrupting mitosis or contractile ring assembly. (R)-(+)-Blebbistatin is suitable as a negative control for (S)-(-)-Blebblastatin.

Ceftobiprole medocaril sodium (BAL5788) is a parenteral prodrug of Ceftobiprole, a pyrrolidinone cephalosporin administered intravenously. As a broad-spectrum cephalosporin, Ceftobiprole exhibits high in vitro activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Staphylococci (VRSA), and penicillin-resistant Streptococci. Additionally, it is effective in inhibiting both gram-positive and gram-negative pathogens.

Ceftobiprole (Ro 63-9141) is a β-lactam antibacterial agent that exhibits potent bactericidal activity by binding to PBPs, inhibiting transpeptidation and formation of bacterial cell walls, leading to cell lysis and death, with a MIC90 value of 2 μg mL against methicillin-resistant Staphylococcus aureus.
