Field of application
Targocil is a novel antibiotics against Methicillin-resistant Staphylococcus aureus (MRSA).

Formula: C21H22ClN5O4S

Description: Targocil functions as a bacteriostatic inhibitor of wall teichoic acid (WTA) biosynthesis which can inhibit the growth of methicillin-susceptible S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA) with MIC90s of 2 μg/ mL for both MRSA and MSSA.
Target: MIC90: 2 μg/mL (MSSA), 2 μg/mL (MRSA)[1]
In Vitro: MICs of Targocil against S. aureus strains Newman, MW2, MG2375, and MG2389 are 1 μg/mL for all strains. Targocil shows excellent activity against S. aureus isolates from suspected cases of bacterial keratitis, including both MSSA and MRSA isolates, with MICs that range from 1 to 2 μg/ mL. Targocil, a derivative of 1835F03, exhibits better activity against all keratitis isolates than the original lead compound, 1835F03. Bovine serum exhibits a detectable but moderate inhibitory effect on the in vitro antimicrobial activities of both 1835F03 and Targocil, increasing the MICs of both by 4- to 8-fold. Compare to the vehicle alone, Targocil at 5 μg/mL exhibits little toxicity for HCECs, even after 24 h of exposure. However, 40 μg/mL Targocil shows toxicity at all time points tested. Targocil at levels equal to 10×MIC in vitro readily inhibits growth of Newman and MG2375 in the presence of HCECs[1]
Cell Assay: Log-phase strains MG2375, MG2389, Newman, and MW2 are collected and adjusted to a concentration of 2×108 CFU/mL. After the treatment of bacterial cultures with Targocil at 10×MIC for 1 h, the cells are diluted 1:1,000 in fresh medium and then incubated and plated at the appropriate time points for viability determination. The postantibiotic effect (PAE) is calculated by the standard equation T-C, where T is the time required for the CFU count in the test culture to increase 10-fold above the count observed immediately after drug removal, and C is the time required for the count of the untreated control to increase 10-fold under the same conditions[1].

DC82301 IC-8 IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC46471 RP101988 RP101988, the major active metabolite of Ozanimod, is a selective, potent S1PR1 (sphingosine-1-phosphate receptor 1) agonist, with EC50s of 0.19 nM and 32.8 nM for S1PR1 and S1PR5, respectivlely.
DC45184 Hydrofurimazine Hydrofurimazine is a NanoLuc substrate whose enhanced aqueous solubility allows delivery of higher doses to mice. Hydrofurimazine enables sensitive bioluminescence imaging for either prolonged light production of high sensitivity.
DC37901 PD-173212 PD-173212 is a small molecule N-type calcium channel blocker.
DC37333 N,N-Diethyl-p-toluamide N,N-Diethyl-p-toluamide is a mosquito repellent.
DC37321 AI3-15902 AI3-15902 is a biochemical.
DC37283 Methyl phenylcarbamate Methyl phenylcarbamate is a biochemical.
DC37252 Ampyrone Ampyrone is a metabolite of AMINOPYRINE with analgesic and anti-inflammatory properties. It is used as a reagent for biochemical reactions producing peroxides or phenols. Ampyrone stimulates LIVER MICROSOMES and is also used to measure extracellular water.
DC37245 Piperonyl butoxide Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is a waxy white solid. It is a synergist. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.[1] It is a semisynthetic derivative of safrole.
DC36443 DC-Chol DC-Chol is a cationic cholesterol derivative. DC-Chol, as a component of lipoplexes with DOPE, has been used for transfection of mRNA into A549 cells without affecting cell viability. Incubation of DC-chol/DOPE liposomes or lipoplexes with human whole blood has no effect on neutrophil elastase or β-thromboglobulin levels or the number of platelets and red and white blood cells, indicating hemocompatibility. DC-Chol has also been widely used in the synthesis of liposomes for the delivery of siRNA, DNA, and chemotherapeutic agents into cells and mice.
