Medchemexpress LLC Aztreonam | 78110-38-0 | 99.6% | 1 ML
Aztreonam is a synthetic monocyclic beta-lactam antibiotic with a high affinity for penicillin-binding protein 3 (PBP-3). It was approved by the U.S. Food and Drug Administration in 1986. This antibiotic is resistant to some beta-lactamases but can be inactivated by extended-spectrum beta-lactamases. It shows no useful activity against gram-positive or anaerobic microorganisms. Aztreonam inhibits mucopeptide synthesis in the bacterial cell wall, thereby blocking peptidoglycan crosslinking. It has a mild affinity for PBP-1a and is largely ineffective against gram-positive and anaerobic bacteria due to poor binding to their penicillin-binding proteins. Aztreonam is bactericidal, though less so than some cephalosporins.

Medchemexpress LLC Thalidomide-NH-PEG3-COOH | 2375283-62-6 | 98.9% | 477.46 | C22H27N3O9 | 5 MG
Thalidomide-NH-PEG3-COOH is a synthesized E3 ligase ligand-linker conjugate that combines a thalidomide-derived cereblon ligand with a three-unit polyethylene glycol (PEG3) linker terminating in a carboxylic acid. It is intended as a modular building block for PROTAC development to recruit CRBN and enable linker attachment to target-binding ligands.
- Designed for PROTAC assembly and CRBN recruitment.
- Contains a PEG3 linker terminating in a carboxylic acid for facile conjugation.
- Incorporates a thalidomide-based cereblon ligand.
- High chemical purity (≈98.9%).
- Suitable for medicinal chemistry and chemical biology applications.
