چکیده

Betulin derivatives are a widely studied group of compounds of natural origin due to their wide spectrum of biological activities. This paper describes new betulin derivatives, containing a phosphonate group. The allyl-vinyl isomerization and synthesis of acetylenic derivatives have been reported. Structural identification of products as E and Z isomers has been carried out using ¹H-, (13)C-, (31)P-NMR, and crystallographic analysis. The crystal structure in the orthorhombic space group and analysis of crystal packing contacts for 29-diethoxyphosphoryl-28-cyclopropylpropynoyloxy-lup-20E(29)-en-3β-ol 8a are reported. All new compounds were tested in vitro for their antiproliferative activity against human T47D (breast cancer), SNB-19 (glioblastoma), and C32 (melanoma) cell lines.

Synthesis, structure and cytotoxic activity of new acetylenic derivatives of betulin.

A new series of betulin derivatives containing one or two pharmacophores bearing an acetylenic and carbonyl function at the C-3 and/or C-28 positions has been synthesized and characterized by ¹H- and ¹³C-NMR, IR, MS and elemental analyses. The crystal structure of 28-O-propynoylbetulin was determined by X-ray structural analysis. All new compounds, as well as betulin, were tested in vitro for t...

Novel N-2-(Furyl)-2-(chlorobenzyloxyimino) ethyl Piperazinyl Quinolones: Synthesis, Cytotoxic Evaluation and Structure-activity Relationship

Quinolone antibacterials are one of the most important classes of pharmacological agents known as potent inhibitors of bacterial DNA gyrase and topoisomerase IV that efficiently inhibit DNA replication and transcription by generating several double-stranded DNA break. Some quinolone derivatives demonstrated inhibitory potential against eukaryote topoismarase II and substantial dose-dependent cy...

Antiproliferative Activity of Novel Acetylenic Derivatives of Betulin against G-361 Human Melanoma Cells.

Acetylenic derivatives of betulin were tested in vitro for their antiproliferative activity against G-361 human melanoma cells. Two types of betulin derivatives were studied: monoesters, obtained by modification of the hydroxyl group at C-28 position, and diesters modified at both C-28 and C-3 positions. To assess cell proliferation, a colorimetric sulforhodamine B based method was used. All th...

Novel Triazole Hybrids of Betulin: Synthesis and Biological Activity Profile.

Betulin derivatives containing a 1,2,3-triazole ring possess a wide spectrum of biological activities, including antiviral, anticancer, and antibacterial activity. A series of novel triazoles were prepared by the 1,3-dipolar cycloaddition reaction between the alkyne derivatives of betulin and organic azides. The chemical structures of the obtained compounds were defined by ¹H and 13C NMR, IR, a...
