This work describes the syntheses and antitumoral properties of five prenyl compounds from which antiproliferative activities were predicted by using the TOPS-MODE approach, a computational method for drug design. The syntheses of 2-(3-methylbut-2-enyloxy)acetophenone (2), 2-hydroxy-5-(3-methylbut-2-enyl)acetophenone (3), 2-hydroxy-3-(1,1-dimethylallyl)acetophenone (4), and 5-(3-methylbut-2-eny...

An efficient and divergent synthesis of polyol subunits utilizing a phosphate tether-mediated, one-pot, sequential RCM/CM/reduction process is reported. A modular, 3-component coupling strategy has been developed, in which, simple "order of addition" of a pair of olefinic-alcohol components to a pseudo-C 2-symmetric phosphoryl chloride, coupled with the RCM/CM/reduction protocol, yields five po...

The synthesis of 5'-triphosphates of 4-thiouridine, 2-thiocytidine, 5-bromocytidine, and [6N]adenosine is described. All compounds are characterized by chromatographic and spectral data. Phosphorylation of corresponding nucleotides was performed using phosphoryl chloride and con­ densation with pyrophosphate. Intermediates were not isolated. The final products were purified by chromatography an...

In this work, series of new chalcones derived from indole compounds were synthesized. the first compound 2-(1,1-dimethyl-1,3-dihydro-2H-benzo[e]indol-2-ylidene)malonaldehyde was synthesized reaction 1,1,2-trimethyl-1H-benzo[e]indole with Phosphoryl chloride in presence (DMF). Schiff base (C2) prepared by 2-(1,1-dimethyl-1,3-dihydro-2H-benzo[e]indol-2-ylidene) malonaldehyde 3-amino acetophenone ...

Calcium-bound phosphoryl oligosaccharides (POs-Ca) were prepared from potato starch. Their solubility and in situ absorbability as a calcium source were investigated by comparing with the soluble calcium compounds, calcium chloride and calcium lactate, or insoluble calcium compounds, calcium carbonate and dibasic calcium phosphate. The solubility of POs-Ca was as high as that of calcium chlorid...

DL-1-(2,3-Dihydroxypropyl)thymine was prepared by Hilbert-Johnson reaction of 2,4-dinethoxy-5-methylpyrimidine with allyl bromide followed by the osmium tetroxide catalyzed hydroxylation of the l-allyl-4-methoxy-5-methylpyrimidin-2-one obtained as an intermediate. The D-glycero enantiomer, R-1-(2,3-dihydroxypropyl)thymine and the corresponding 1-substituted uracil derivative were prepared from ...

The title compound, C(20)H(26)NO(4)P, has been obtained by the reaction of benzoyl chloride and diisoprop-yl[amino-(phen-yl)meth-yl]phospho-nate. The dihedral angle between the planes of the benzoyl-amino group and the phenyl ring is 77.0 (2)°. The crystal structure is stabilized by strong inter-molecular N-H⋯O hydrogen bonds between the doubly bonded phosphoryl O atom and the amide N atom whic...
