Hydrogen phosphates: Self initiated organocatalysts for the controlled ring-opening polymerization of cyclic esters
Malik, Payal,Chakraborty, Debashis
, p. 32 - 41 (2013/07/19)
A series of arylhydrogenphosphates and aryldihydrogenphosphates was synthesized and characterized using spectroscopic methods and single crystal X-ray diffraction. These compounds were assessed as catalysts towards the ring-opening polymerization and proved to be potent organocatalysts for the ring-opening polymerization of cyclic esters. The bulk polymerizations were performed in the absence of external initiator. The polymerization proceeds in a controlled fashion which leads to well defined polyesters with narrow molecular weight distributions. In the post polymerization experiments, kinetics, mechanism and monomer concentration effects were investigated. The kinetic results have confirmed the pseudo-living character of the polymerizations and mechanistic studies suggest that the polymerization operates through a cationic mechanism.
The application of phosphoramidate protide technology to acyclovir confers anti-HIV inhibition

Recently, it has been reported that phosphorylated acyclovir (ACV) inhibits human immunodeficiency virus type 1 (HIV-1) reverse transcriptase in a cell-free system. To deliver phosphorylated ACV inside cells, we designed ACV monophosphorylated derivatives using ProTide technology. We found that the L-alanine derived ProTides show anti-HIV activity at noncytotoxic concentrations; ester and aryl variation was tolerated. ACV ProTides with other amino acids, other than L-phenylalanine, showed no detectable activity against HIV in cell culture. The inhibitory activity of the prodrugs against herpes simplex virus (HSV) types -1 and -2 and thymidine kinase-deficient HSV-1 revealed different structure-activity relationships but was again consistent with successful nucleoside kinase bypass. Enzymatic and molecular modeling studies have been performed in order to better understand the antiviral behavior of these compounds. ProTides showing diminished carboxypeptidase lability translated to poor anti-HIV agents and vice versa, so the assay became predictive.
Anti-cancer ProTides: Tuning the activity of BVDU phosphoramidates related to thymectacin

Based on our wide ranging knowledge of phosphoramidate ProTides as anti-viral agents we have tuned the lead anti-cancer agent thymectacin in the ester and amino acid regions and revealed a substantial enhancement in in vitro potency versus colon and prostate cancer cell lines. Twelve analogues have been reported, with yields of 29-78%. The compounds are fully characterised and data clearly reveal the presence of two phosphate diastereoisomers, as expected, in roughly equi-molar proportions. The compounds were evaluated in tissue culture versus three different tumour cell lines, using thymectacin as the control. It is notable that minor structural modification of the parent phenyl methoxyalaninyl structure of thymectacin leads to significant enhancements in potency. In particular, replacement of the methyl ester moiety in the lead by a benzyl ester gave a 175-fold boost in potency versus colon cancer HT115. This derivative emerges as a low micromolar inhibitor of HT115 cells and a new lead for further optimisation.
Anti-proliferative and anti-leukemic activity of DDE46 (compound WHI-07), a novel bromomethoxylated arylphosphate derivative of zidovudine, and related compounds: Studies using human acute lymphoblastic leukemia cells and the zebrafish model
Benyumov, Alexey O.,Venkatachalam, Taracad K.,Grigoriants, Olga O.,Vassilev, Alexei O.,Tibbles, Heather E.,Downs, Suzanne,Dumez, Darin,Uckun, Fatih M.
, p. 114 - 122 (2007/10/03)
The anti-proliferative effects of a novel bromomethoxylated arylphosphate derivative of zidovudine (compound DDE46, CAS 213982-96-8) were first examined in a zebra fish embryo model. DDE46 blocked the cell division at the 2-cell stage of the embryonic development followed by total cell fusion. DDE46 also inhibited the proliferation of the leukemic cell lines NALM-6 and MOLT-3. DDE46 enhanced the activity of the pro-apoptotic enzymes Caspase-3, Caspase-6, Caspase-8, and Caspase-9 leading to the apoptotic death of the leukemic cell line Jurkat. These results justify the further development of this agent as a new anti-leukemic drug candidate. ECV · Editio Cantor Verlag, Aulendorf (Germany).

Phosphoramidate derivatives of nucleotides and their use in the treatment of cancer are described. The base moieties of, for example, each of deoxyuridine, cytarabine, gemcitabine and citidine may be substituted at the 5-position. The phosphoramidate moiety has attached to the P atom an aryl-O moiety and an α-amino acid moiety. The α-amino acid moiety may correspond to or be derived from either a naturally occurring or a non-naturally occurring amino acid.
Intracellular delivery of bioactive AZT nucleotides by aryl phosphate derivatives of AZT
McGuigan,Pathirana,Balzarini,De Clercq
, p. 1048 - 1052 (2007/10/02)
Novel aryl phosphate derivatives of the anti-HIV nucleoside analogue AZT have been prepared by phosphorochloridate chemistry. These materials were designed to act as membrane-soluble prodrugs of the bioactive free nucleotides. In vitro evaluation revealed the compounds to have a pronounced, selective anti-HIV activity in CEM cells; the magnitude of the biological effect varied considerably depending on the nature of the phosphate blocking group. Moreover, several of the compounds retain marked antiviral activity in TK- (thymidine kinase-deficient) mutant CEM cells in which AZT was virtually inactive. These data strongly support the hypothesis that the AZT phosphate derivatives exert their biological effects via intracellular release of AZT nucleotide forms and suggest that the potential of nucleoside drugs in antiviral chemotherapy may be enhanced by suitable nucleotide delivery strategies.
