Radiosensitizing activity of novel small molecule BRCA1 and DNA-PK inhibitors in lung and colon carcinoma

open access: yesJournal of Radiation Research and Applied Sciences, 2017
The DNA dependant protein kinase (DNA-PK) enzyme plays a major part in the repair of double stranded breaks induced by radiation and hence in the radio-resistance of tumour cells.

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

open access: yesMedicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),

Synthesis and characterization of novel mussel-inspired benzoxazines bythiol-benzoxazine chemistry

open access: yesTURKISH JOURNAL OF CHEMISTRY, 2019
A catechol-based benzoxazine copolymer is reported via a new approach using an oxazine-thiol reaction.The main chain benzoxazine precursor was obtained via the classic benzoxazine synthesis methodology using the raw chemicals catechol, formaldehyde, and 4,7,10-trioxa-1,13-tridecanediamine. The countercomponent was synthesized from poly(ethylene glycol)

A study on the co-reaction of benzoxazine and triazine through a triazine-containing benzoxazine

open access: yesRSC Advances, 2016
To study the co-reaction of benzoxazine and triazine, a triazine-containing benzoxazine (P-tta) was prepared through nucleophilic substitution of 4-(2H-benzo[e][1,3]oxazin-3(4H)-yl)phenol (P-ap) with 2,4,6-trichloro-1,3,5-triazine.
