quinoline/sarcoma

Effects of quinoline and captafol, both of which are hemangiocarcinogenic agents, were investigated in spontaneously hypertensive rats (SHR). Male SHR and Wistar Kyoto rats (WKY), the parent strain of SHR, were administered quinoline (0.2%) or captafol (0.15%) supplemented in the diet for 32 weeks.

BACKGROUND Soft tissue sarcoma accounts for less than 1% of all malignant neoplasms and is comprised of a very heterogeneous group of tumors with over 50 different subtypes. Due to its diversity and rarity, developing new therapeutics has been difficult, at best. The standard of care in the

The carcinogenicity of quinoline was examined by administrating quinoline in the drinking water to groups of 50 F344/DuCrj rats and 50 Crj: BDF1 mice of each sex. In rats, the doses of quinoline were 0, 200, 400, and 800 ppm for males and 0, 150, 300, and 600 ppm for females. In male rats,

Novel 5H-indolo[2,3-b]quinoline O-aminoglycosides were synthesized in order to check the hypothesis that the construction of hybrids composed of the active 5H-indolo[2,3-b]quinoline chromophore and daunosaminyl or acosaminyl moiety may result in the cytotoxic activity of the obtained derivatives

A series of novel 6H-indolo[2,3-b]quinoline derivatives, substituted at C-2, C-9 or N-6 position with dialkyl(alkylamino)alkyl chains differing in the number of methylene groups, was prepared. These compounds were evaluated in vitro for their antimicrobial and cytotoxic activity against several cell

OBJECTIVE The resistance to chemotherapeutic drugs is a major problem for successful cancer treatment. Multidrug resistance (MDR) phenotype is characterized by over-expression of P-glycoprotein (P-gp) on the cancer cell plasma membrane that extrudes drugs out of the cells. Therefore, novel MDR

Several fused tri- and tetracyclic quinolines (I and II) with [2-methoxy-4-[(methylsulfonyl)amino]phenyl]amino or [3-(N,N-dimethylamino)propyl]amino side chains were prepared, and their DNA intercalative properties, KB cytotoxicity, antitumor activity (P388 leukemia), and ability to induce

A number of 2-chloromethyl and 2-bromomethyl derivatives of naphthoquinones, quinolinediones, and naphthazarins were designed and synthesized as potential bioreductive alkylating agents, and the antitumor activity of these compounds was assessed in mice bearing Sarcoma 180 ascites cells. The results

Jaw bones differ embryologically from limb bones and the axial skeleton as they are derived from migrating neural crest cells and are not preformed in cartilage as are the latter bone types. The purpose of the present study was to determine whether this embryologically different nature implied a

The curiosity and attention that researchers have devoted to alkaloids are due to their bioactivities, structural diversity, and intriguing chemistry. Marine-derived macrocyclic alkaloids (MDMAs) are considered to be a potential source of drugs. Trabectedin, a tetrahydroisoquinoline derivative, has

Styrylquinoline derivatives, known to be potent inhibitors of HIV-1 integrase, have been experimentally tested for their inhibitory effect on the disintegration reaction catalyzed by catalytic cores of HIV-1 and Rous sarcoma virus (RSV) integrases. A modified docking protocol, consisting of coupling

Cancer is a leading cause of death worldwide. Multidrug resistance (MDR) is a main reason of chemotherapy failure in many patients and is often related to overexpression of ATP-binding cassette (ABC) transporters, including P-glycoprotein (P-gp/ABCB1). Agents that are capable of modulation of the

The structural parameters necessary for the antineoplastic potency of a new class of anticancer agents, arylsulfonylhydrazones of 2-formylpyridine N-oxide, were examined in mice bearing Sarcoma 180 ascites cells. The findings indicated that (a) replacement of the pyridine ring with benzene,

8-Hydroxy-2-[2-(3-hydroxy-4-methoxyphenyl)ethenyl]-7-quinoline carboxylic acid and 8-hydroxy-2-[2-(3-methoxy-4-hydroxyphenyl)ethenyl]-7-quinoline carboxylic acid inhibit the processing and strand transfer reactions catalyzed by HIV-1 integrase with an IC50 of 2 microM. Some of their spectral
