comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولPotent antileukemic activity of the novel agents norsegoline and dibezine.
We examined the effect of norsegoline, a natural marine product, and dibezine, a synthetic product, on the survival of human myeloid progenitor cells [colony-forming unit-cells (CFU-C)] from normal individuals and from 10 patients with Philadelphia-positive chronic myelogenous leukemia (CML) in chronic phase and blastic crisis. We compared their effect to the effect of IFN-alpha. Norsegoline, d...
متن کاملAntileukemic activity of lignans and phenylpropanoids of Cinnamomum parthenoxylon.
In this study, we evaluated the in vitro cytotoxicity of fractions and isolated constituents from Cinnamomum parthenoxylon woods against human leukemia HL-60 and U937 cells. The n-Hex, EtOAc, and MeOH-H2O fractions of the woods inhibited cell proliferation in both cell lines. Our phytochemical investigation of the n-Hex and EtOAc fractions led to the isolation of lignans and phenylpropanoids, w...
متن کاملAntileukemic activity of Tillandsia recurvata and some of its cycloartanes.
BACKGROUND Approximately 250,000 deaths were caused by leukemia globally in 2012 and about 40%-50% of all leukemia diagnoses end-up in death. Medicinal plants are a rich source for the discovery of new drugs against leukemia and other types of cancers. To this end, we subjected the Jamaican ball moss (Tillandsia recurvata) and its cycloartanes, as well as some analogs, to in vitro screening aga...
متن کاملAntileukemic and immunosuppressive activity of 2-chloro-2'-deoxyadenosine.
The adenosine deaminase-resistant purine deoxynucleoside 2-chloro-2'-deoxyadenosine (CdA) is markedly toxic in vitro to nondividing and proliferating normal human lymphocytes and to many leukemia cell specimens. The CdA is also effective against mouse L1210 leukemia in vivo. The present investigations have examined the pharmacology, chemotherapeutic activity, and toxicity of CdA in nine patient...
