Phylogenetic analysis of HTLV-I variants persisting among population of Turkmenistan and the Republic of Georgia (situated on both sides of the Caspian Sea, not far from a known HTLV-I cluster in Northern Iran) has been carried out. HTLV-I isolates from the above countries were obtained in the course of seroepidemiological investigations. In all, 1,510(More)
We describe the synthesis of derivatives of 4,11-diaminonaphtho[2,3-f]indole-5,10-dione and their cytotoxicity for human tumor cells that express major determinants of altered anticancer drug response, the efflux pump P-glycoprotein, and non-functional p53. Nucleophilic substitution of methoxy groups in 4,11-dimethoxynaphtho[2,3-f]indole-5,10-dione with(More)
The reactions of picolinyl and 4-chloropicolinyl chlorides with methyl esters of S-methyl-l-cysteine, l- and d-methionine, and l-histidine afforded a series of functionalized carboxamides, which readily formed pincer-type complexes upon interaction with PdCl2(NCPh)2 in solution under mild conditions. The direct cyclopalladation of the ligands derived was(More)
A series of new fluorescent symmetric dimeric bisbenzimidazoles DBP(n) bearing bisbenzimidazole fragments joined by oligomethylene linkers with a central 1,4-piperazine residue were synthesized. The complex formation of DBP(n) in the DNA minor groove was demonstrated. The DBP(n) at micromolar concentrations inhibit in vitro eukaryotic DNA topoisomerase I(More)
Background Epidemics caused by the reemergence of Zika virus (ZIKV) warrant the need to develop new diagnostic measures to complement currently used detection methods. In this study, we explored the detection of ZIKV antigen in a defined leukocyte subset from patients' whole-blood specimens. Methods Whole-blood samples were obtained at the acute and early(More)
The efficacy of anthracycline based anticancer drugs is limited by pleiotropic drug resistance of tumor cells. Aiming at the design of anthracyclinone congeners capable of circumventing drug resistance, we synthesized naphthoindole containing derivatives of tryptophan and tryptamine. In doing so we adapted the traditional, gramine based approach for(More)
Zika virus (ZIKV, genus Flavivirus) has emerged as a major mosquito-transmitted human pathogen, with recent outbreaks associated with an increased incidence of neurological complications, particularly microcephaly and the Guillain-Barré syndrome. Because the virus has only very recently emerged as an important pathogen, research is being hampered by a lack(More)
