Cephradine sodium is the salt form of Cephradine (free base), a semi-synthetic cephalosporin antibiotic. Cefradin inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Cefradin may interfere with autolysin inhibitors.
Tyvelose is an unusual 3,6-dideoxyhexose terminal sugar and the immunodominant component of glycoprotein antigens in the parasitic helminth T. spiralis, which is responsible for trichinosis in humans. It is produced in high amounts by the infective larva and is immunodominant during the muscle stage of infection. Mice immunized with tyvelose-BSA produce IgG1 antibodies to tyvelose but are not resistant to infection by T. spiralis. Tyvelose-specific antibodies (2.5 mg/20 g) administered to rat pups leads to expulsion of first stage larvae from the intestine within one hour.
MMV674850 exhibits potency against asexual stage parasites, with IC50 values of 2.7 and 4.5 nM. Furthermore, it demonstrates a preferential affinity for early-stage gametocytes, displaying an IC50 value of 4.5 ± 3.6 nM, compared to late-stage gametocytes with an IC50 value of 28.7 ± 0.2 nM.
Vanilmandelic acid, L-(+)- is a chemical intermediate in the synthesis of artificial vanilla flavorings and is an end-stage metabolite of the catecholamines, epinephrine, and norepinephrine. It is produced via intermediary metabolites.
Ansatrienin B is an ansamycin antibiotic and antifungal agent first isolated from S. collinus and S. rishiriensis., In fetal rat long bones, it is an inhibitor of parathyroid hormone-induced calcium release (IC50 = 21 nM), which is a measure of bone resorption, and pp60c-src kinase (IC50 = 50 nM). It is an inhibitor of translation at the protein synthesis stage by specific inhibition of L-leucine incorporation (IC50 = 58 nM in A549 cells). It also inhibits TNF-α-induced expression of intercellular adhesion molecule-1 (ICAM-1; IC50 = 300 nM). Early in vitro studies showed that ansatrienin B potentiates the chemotherapeutic action of 5-fluorouracil , cisplatin , bleomycin , mitomycin C , and 6-mercaptopurine. Ansatrienin B is a hydroquinone form of ansatrienin A .
Lipid-derived lipoxins are produced at the site of vascular and mucosal inflammation where they down-regulate polymorphonuclear leukocyte recruitment and function. 15(R)-Lipoxin A4 (15(R)-LXA4) is derived from the aspirin-triggered formation of 15(R)-HETE from arachidonic acid. [1] [2] 15(R)-LXA4 inhibits LTB4-induced chemotaxis, adherence, and transmigration of neutrophils with twice the potency of LXA4 demonstrating activity in the nM range.[2] [3] The anti-inflammatory effects of aspirin may be ascribed in part to the ability of 15(R)-LXA4 to regulate leukocyte function.[4] 15(R)-LXA4 is reported to promote resolution of inflammation in LPS-treated stromal cells derived from intermediate-stage diseased supraspinatus tendons as evidenced by increased expression of the STAT-6 pathway target genes, ALOX15 and CD206.[5]
PEN-866 is a potential agent for controlling early stage tumor growth for non-small cell lung cancer (NSCLC). PEN-866 is a novel esterase-cleavable conjugate of an HSP90i and a topoisomerase I inhibitor, SN-38
Albaspidin AA displays strong antibacterial activity against the vegetative form of P. larvae (MIC ranging from 0.168-220 uM). It may have in vitro nematocidal activity against L4 stage larvae.
Hyptadienic acid exhibits moderate cytotoxicity against HepG2 cells.It also shows a marked anti-inflammatory effect, it also exhibits strong antitumor-promoting activity in an in vivo two-stage carcinogenesis test of mouse tumor by using 7,12-dimethylbenz
5-hydroxy Thiabendazole (5-OH TBZ) is a major metabolite of the anthelmintic thiabendazole . Unlike thiabendazole, 5-OH TBZ has no effect on the growth of third-stage A. caninum larvae.
