Biphalin, a dimeric enkephalin analog, is under investigation as a potential, long-lasting medication of pain associated with chronic diseases, like cancer or AIDS. The role of cytokines, and splenocytes in anti-Friend leukemia virus (FLV) activity of biphalin, a synthetic opioid, and AZT was investigated in vitro. Mouse splenocytes inhibited FLV replication in Mus dunni (Dunni) cells when they...
BACKGROUND High expression of telomerase and Bcl-2 are reported in hepatocellular carcinoma. Some anticancer drugs show their effects through reduction of these factors. In this study, it was aimed to investigate the effects of a new synthetic compound, platinum azidothymidine, on inhibition of telomerase and Bcl-2 expression in hepatocellular carcinoma compared to azidothymidine. METHODS To ...
PURPOSE Classical pharmacology allows the use and development of conventional phytomedicine faster and more economically than conventional drugs. This approach should be tested for their efficacy in terms of complementarity and disease control. The purpose of this study was to determine the molecular mechanisms by which nimbolide, a triterpenoid found in the well-known medicinal plant Azadirach...
Maternal-fetal HIV-1 transmission can be prevented by administration of AZT, alone or in combination with other antiretroviral drugs to pregnant HIV-1-infected women and their newborns. In spite of the benefits deriving from this life-saving prophylactic therapy, there is still considerable uncertainty on the potential long-term adverse effects of antiretroviral drugs on exposed children. Clini...
The replication of recombinant multidrug-resistant HIV-1 clones modeled on clinically derived resistant HIV-1 strains from patients receiving long-term combination therapy with zidovudine (AZT) plus 2',3'-dideoxycytidine was found to regain sensitivity to AZT and stavudine (D4T) as a consequence of a pharmacologically induced decrease in de novo dTMP synthesis. The host-cell system used was phy...
Thymidine analogue-associated mutations (TAMs) in reverse transcriptase (RT) of the human immunodeficiency virus type 1 (HIV-1) cause resistance to 3'-azido-3'-deoxythymidine (AZT) through excision of the incorporated monophosphate. Mutations in the connection domain of HIV-1 RT can augment AZT resistance. It has been suggested that these mutations compromise RNase H cleavage, providing more ti...
زمینه و هدف: لوسمی پرومیلوسیتیک حاد(apl) یکی از لوسمی های شایع است که حدود 10-5 % از بیماران مبتلا به لوسمی حاد میلوبلاستی را در برمی گیرد. در درمان بیماران از atra و اخیرا از آرسنیک استفاده می شود. آترا باعث مقاومت به درمان و آرسنیک در دوز بالا سمی است. azt با القاء اثرات مختلف باعث مرگ سلولی می شود. هدف از این مطالعه بررسی اثر azt ، مهار کننده تلومراز، بر رده سلولی nb4 (رده سلولی apl) جهت ...
