Ionic liquid mediated one-pot synthesis of 6-aminouracils

A novel, one-pot synthesis of 6-aminouracils via in situ generated ureas and cyanoacetylureas in the presence of an ionic liquid catalyst, 1,1,3,3-tetramethylguanidine acetate, is described. The catalyst can be recycled for five consecutive runs without loss of activity. The mechanism for the ring closure of cyanoacetylurea to 6-aminouracil is also discussed.

COMPOUNDS USEFUL IN DELIVERING ANTI-NEOPLASTIC THERAPY AND DIAGNOSTIC IMAGING TO HYPOXIC CELLS AND METHODS OF USE THEREOF

Described herein are compounds that permeate cell membranes via specific hypoxia-upregulated transporters in hypoxic cells, get bioreductively activated intracellularly, and bind selectively to subcellular macromolecules to demonstrate hypoxia-specific ac

Synthesis and hypoxic-cytotoxic activity of some 3-amino-1,2,4-benzotriazine-1,4-dioxide derivatives

A series of 3-amino-1,2,4-benzotriazine-1,4-dioxide derivatives 1 have been synthesized and evaluated for their cytotoxic activity in vitro against human leukemia cell lines: Molt-4, K562, HL60, human liver cancer cell Hep-G2, human prostate cancer cell PC-3 in hypoxia. Most of the compounds showed more potent activity than TPZ. Compounds 1i and 1m displayed encouraging superior activity against Molt-4 and HL-60 cell lines. Three potential derivatives received the test of the activity in hypoxia and in normoxia against Molt-4 and HL-60 cell lines and showed obvious hypoxia selectivity. Further mechanism study revealed that the cytotoxic activities of compounds 1i and 1k in Molt-4 cells might be mediated by modulation of p53 protein expression and mitochondrial membrane potential (ΔΨm).

Reactions of arylazosulfones with the conjugate bases of (tert-butoxycarbonyl)methyl and tosylmethyl isocyanide. Synthesis of substituted 1-arylimidazoles

The reactions of arylazosulfones 1 (ArN = NSO2Ar') with the potassium salts of (tert-butoxycarbonyl)methyl 2 and tosylmethyl isocyanide 3 in DMSO afford 4,5-bis(tert-butoxycarbonyl)- 4 and 4-tosyl-1-arylimidazoles 5, respectively. Yields of imidazoles 4 and 5 vary from moderate to excellent depending on the nature both of Ar in 1 and of the nucleophile (2 or 3) employed. A comparison of the results obtained with those relevant to the reactions of the same nucleophiles with nitrosobenzene in analogous experimental conditions provides useful mechanistic indications on the transformation of 1 to 4 or 5.

N-Nitroaryl-N-halosulfonyl ureas

N-o-nitro-phenyl- or -naphthyl-N'-halogensulfonyl ureas which may be substituted in their aromatic rings by a further nitro group (and the phenyl ureas also by fluoro, chloro, bromo, lower alkyl, lower alkoxy, trifluoromethyl, cyano or phenyl) are obtaine
