Ceftazidime (GR20263) is a beta-lactam, cephalosporin antibiotic with bactericidal activity.

Ceftazidime Pentahydrate is a cephalosporin antibiotic with activity against gram-negative bacilli, including Pseudomonas aeruginosa, and is used in the study of infectious diseases.

CAY10742 is an orally bioavailable oxadiazole antibiotic.1It is active against the Gram-positive bacteriaS. aureus,S. epidermidis,S. haemolyticus,B. cereus,B. licheniformis,E. faecalis, andE. faecium(MICs = 1-4 μg/ml), including laboratory strains and clinical isolates with varying degrees of resistance to methicillin, vancomycin, linezolid, and other antibiotics. CAY10742 (40 mg/kg) reduces the number of bacteria in mouse neutropenic thigh models of linezolid-sensitive or -resistant methicillin-resistantS. aureus(MRSA) infection. 1.Boudreau, M.A., Ding, D., Meisel, J.E., et al.Structure-activity relationship for the oxadiazole class of antibacterialsMed.

DHFR-IN-9 (compound 8A), a dihydrofolate reductase (DHFR) inhibitor, impedes purine and thymidylate biosynthesis, pivotal in cell proliferation and growth. It demonstrates potency against methicillin-resistant Staphylococcus aureus (MRSA) ATCC 43300 with an IC50 of 0.25 μg mL and exhibits anti-infective properties in mouse systemic and thigh infection models at doses of 2.5 mg kg and 5 mg kg administered intraperitoneally (ip). Furthermore, DHFR-IN-9 shows greater anticancer efficacy in a mouse breast cancer model compared to paclitaxel (Y-B0015), at a regimented dosage of 2.5 mg kg ip every three days [1].
