1,4-Diazabicyclo[2.2.2]octane (280-57-9)  
DABCO  ·  triethylenediamine  ·  1,4-diazabicyclo(2.2.2)octane
DABCO (1,4-diazabicyclo[2.2.2]octane) is an organic compound with the formula N2(C2H4)3. This colorless solid is a highly nucleophilic amine, which is used as a catalyst and reagent in polymerization and organic synthesis. Quinuclidine has a similar structure, with one of the nitrogen atoms replaced by a carbon atom.
flumequine (42835-25-6)  
R 802  ·  Apurone  ·  R-802
Flumequine is a synthetic fluoroquinolone antibiotic used to treat bacterial infections. It is a first-generation fluoroquinolone antibacterial that has been removed from clinical use and is no longer being marketed. It kills bacteria by interfering with the enzymes that cause DNA to unwind and duplicate.
praziquantel (135526-78-2, 55268-74-1, 57452-31-0)  
Biltricide  ·  Droncit  ·  EMBAY 8440
Praziquantel, sold under the brandname Biltricide among others, is a medication used to treat a number of types of parasitic worm infections. Specifically it is used for schistosomiasis, clonorchiasis, opisthorchiasis, tapeworm infections, cysticercosis, hydatid disease, and other fluke infections. It should not be used for worm infections of the eye.
2-thiouracil (141-90-2)  
Thiouracil refers both to a specific molecule consisting of a sulfated uracil, and a family of molecules based upon that structure.
9-AMINOACRIDINE (90-45-9)  
Aminoacridine  ·  Aminacrine  ·  Aminoacridine Hydrochloride
9-Aminoacridine is a highly fluorescent dye used clinically as a topical antiseptic and experimentally as a mutagen, an intracellular pH indicator and a negative mode small molecule MALDI matrix.
1,6-Anhydro-beta-D-glucopyranose (498-07-7)  
Levoglucosan (C6H10O5) is an organic compound with a six-carbon ring structure formed from the pyrolysis of carbohydrates, such as starch and cellulose. As a result, levoglucosan is often used as a chemical tracer for biomass burning in atmospheric chemistry studies, particularly with respect to airborne particulate matter. Along with other tracers such as potassium, oxalate, and gaseous acetonitrile, levoglucosan has been shown to be highly correlated with regional fires.

Dihydroartemisinin (also known as dihydroqinghaosu, artenimol or DHA) is a drug used to treat malaria. Dihydroartemisinin is the active metabolite of all artemisinin compounds (artemisinin, artesunate, artemether, etc.) and is also available as a drug in itself. It is a semi-synthetic derivative of artemisinin and is widely used as an intermediate in the preparation of other artemisinin-derived antimalarial drugs.
Prulifloxacin (123447-62-1)  
Prulifloxacin is an older synthetic antibiotic of the fluoroquinolone class undergoing clinical trials prior to a possible NDA (New Drug Application) submission to the U.S. Food and Drug Administration (FDA). It is a prodrug which is metabolized in the body to the active compound ulifloxacin.
5,6-Dimethylbenzimidazole (582-60-5)  
5,6-dimethylbenzimidazole hydrochloride
5,6-Dimethylbenzimidazole is a natural benzimidazole derivative. It is a component of vitamin B12 where is serves as a ligand for the cobalt atom. 5,6-Dimethylbenzimidazole is biosynthesized from flavin mononucleotide by the enzyme 5,6-dimethylbenzimidazole synthase.
bicuculline (485-49-4)  
Marbofloxacin (115550-35-1)  
Marbofloxacin is a carboxylic acid derivative third generation fluoroquinolone antibiotic. It is used in veterinary medicine under the trade names Marbocyl,Forcyl and Zeniquin. A formulation of marbofloxacin combined with clotrimazole and dexamethasone is available under the name Aurizon (CAS number 115550-35-1).
2,3,5,6-Tetramethylpyrazine (1124-11-4)
