Novel Tdp1 Inhibitors Based on Adamantane Connected with Monoterpene Moieties via Heterocyclic Fragments

A novel sensor based on a heterocyclic ionophore for cerium (III) analysis in real samples

A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7 M. It has a fast response time (5 s) and can be used for two m...

Anticancer evaluation of novel 1,3,4-trisubstituted pyrazole candidates bearing different nitrogenous heterocyclic Moieties

With the goal of developing novel and potent anticancer therapies, a new set of 1,3,4-trisubstituted pyrazole derivatives linked to different heteroaryl systems at C-4 position were prepared and estimated for their anticancer effects at NCI, USA employing a two stage procedure using 60 various human tumor cell lines. Anticancer evaluation disclosed that, compound 4c displayed super fat potency ...

design and synthesis of novel oxindol derivatives with n-benzylpiperidine and n-benzylpiperazine moieties as cholinesterases inhibitors

Biochemical assays for the discovery of TDP1 inhibitors.

Drug screening against novel targets is warranted to generate biochemical probes and new therapeutic drug leads. TDP1 and TDP2 are two DNA repair enzymes that have yet to be successfully targeted. TDP1 repairs topoisomerase I-, alkylation-, and chain terminator-induced DNA damage, whereas TDP2 repairs topoisomerase II-induced DNA damage. Here, we report the quantitative high-throughput screenin...
