glutathione synthesis in 1

Glutathione synthesis-IN-1 (DC-1) is an inhibitor of glutathione synthesis[1].

ATP Synthesis-IN-1 (Compound 4), a quinoline derivative, potently inhibits PA ATP synthesis with an IC50 of 11.1μg mL and exhibits antibacterial properties. This compound is utilized in studying drug-resistant PA infections [1].

Cylindrospermopsin, a tricyclic uracil derivative, is a cyanobacterial toxin that was first discovered in an algal bloom contaminating a local drinking supply on Palm Island in Queensland, Australia after an outbreak of a mysterious disease. Cylindrospermopsin targets protein and glutathione synthesis in hepatocytes (IC50s = 1.3 and 2.4 µM, respectively), leading to cell death. [1] It has been shown to inhibit the activity of the uridine monophosphate synthase complex with a Ki value of 10 µM.[2] Cylindrospermopsin is genotoxic, inducing DNA damage as evidenced by double strand breaks and reducing cell viability in HepG2 cells at 0.1-0.5 µg/ml.[3]

Aminoethyl-SS-ethylalcohol (Compound 3) is an Alkyl-Chain-based PROTAC linker can be used in the synthesis of PROTACs[1]. Aminoethyl-SS-ethylalcohol is also a glutathione cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[2].

Resolvin conjugate in tissue regeneration 1 (RCTR1) is a specialized pro-resolving mediator (SPM) biosynthesized from docosahexaenoic acid by isolated human macrophages and apoptotic polymorphonuclear (PMN) neutrophils.1It has been found in human spleen and bone marrow.2RCTR1 is produced via lipoxygenase-mediated oxidation of DHA to 7(S)-8-epoxy-17(S)-HDHA, which is conjugated to glutathione.1,2,3RCTR1 (10 nM) increases phagocytosis ofE. colior apoptotic neutrophils in isolated human monocyte-derived macrophages.2It decreases chemotaxis induced by leukotriene B4in isolated human neutrophils when used at a concentration of 10 nM. RCTR1 (1 and 10 nM) accelerates tissue regeneration in planaria. Intraperitoneal administration of RCTR1 (100 ng/animal) shortens the inflammatory resolution period and decreases inflammatory exudate neutrophil infiltration in a mouse model ofE. coli-induced peritonitis. 1.Dalli, J., Ramon, S., Norris, P.C., et al.Novel proresolving and tissue-regenerative resolvin and protectin sulfido-conjugated pathwaysFASEB J.29(5)2120-2136(2015) 2.de la Rosa, X., Norris, P.C., Chiang, N., et al.Identification and complete stereochemical assignments of the new resolvin conjugates in tissue regeneration in human tissues that stimulate proresolving phagocyte functions and tissue regenerationAm.
