Collagenase Enzymes: History, Applications, and Mechanisms of Action 2019-02-21 09:49:35 Since their initial discovery in the 1950s, collagenase enzymes now play a key role in modern scientific research. They have also been approved for therapeutic use when aiming to treat Peyronie’s disease and Dupuytren’s, and also actively support wound healing. There are various c
Polyene Macrolide Antibiotics 2018-12-26 13:31:12 It has been 60 years since the first report of erythromycin in 1952. Over the course of this 60 years the macrolide antibioticsâ€”14- and 16-membered macrolactamsâ€”have been followed at intervals by the lincosamides, streptogramins, azalides and now the ketolides.
Anthracyclines: Anti-Cancer Compounds 2018-12-03 09:00:57 Anthracyclines are anticancer compounds that were originally derived from Streptomyces and their anti-tumor activitieswere established in the 1960s. Anthracyclines are red aromatic polyketides and occur in variety of forms due to the structural differences in the aglycone and the different sugar res
Cefsulodin Sodium: FAQs, Protocols and Applications 2018-11-20 14:45:42 Cefsulodin is a semi-synthetic third generation cephalosporin antibiotic with a structure similar to penicillins and beta-lactams. Cefsulodin is used by the water and dairy industries to test the quality of their products. AG Scientific continues to provide top quality testing reagents and supplies
The Ultimate Guide to Beta Lactamase 2018-11-20 11:30:59 Beta Lactamase Mechanism Beta lactam antibiotics, like cephams and penicillin derivatives, have a four-member cyclic amide ring that inhibits the peptidoglycan layer synthesis in bacteria. A woven complex of sugar and protein pieces, these first-class bactericidal drugs destroy the integrity of
Penicillin: How We Made a Global Savior 2018-11-19 11:00:24 The name 'antibiotic' was first given to the drugs that exhibit 'antibiosis' (meaning 'against life'), by Selman Waksman in 1942. After Vincenzo Tiberio discovered a mold (penicillium) in a well that displayed antibacterial, it led others to find the reasoning behind this. However, it was Alexander
