Role of the NO-GC/cGMP signaling pathway in platelet biomechanics
Platelets. 2024 Dec;35(1):2313359. doi: 10.1080/09537104.2024.2313359. Epub 2024 Feb 14.ABSTRACTCyclic guanosine monophosphate (cGMP) is a second messenger produced by the NO-sensitive guanylyl cyclase (NO-GC). The NO-GC/cGMP pathway in platelets has been extensively studied. However, its role in regulating the biomechanical properties of platelets has not yet been addressed and remains unknown. We therefore investigated the stiffness of living platelets after treatment with the NO-GC stimulator riociguat or the NO-GC activator cinaciguat using scanning ion conductance microscopy (SICM). Stimulation of human and murine pla...

Abacavir induces the transcriptional activity of YY1 and other oncogenic transcription factors in gastric cancer cells
Publication date: Available online 14 December 2019Source: Antiviral ResearchAuthor(s): Ponmathi Panneerpandian, Helen Jemimah Devanandan, Anantharaj Marimuthu, Chandrabose Karthikeyan, Kumaresan GanesanAbstractYin Yang 1 (YY1) is a ubiquitous transcription factor with both transcriptional activating and repressing functions. Targeting YY1 is considered as a potential therapeutic strategy for several malignancies. Telomerase Reverse Transcriptase (TERT) is also considered as a potential target for cancer therapeutics. To enable the large-scale screening and identification of potential YY1 targeting drugs, a gastric cancer ...

Abacavir induces the transcriptional activity of YY1 and other oncogenic transcription factors in gastric cancer cells.
Abstract Yin Yang 1 (YY1) is a ubiquitous transcription factor with both transcriptional activating and repressing functions. Targeting YY1 is considered as a potential therapeutic strategy for several malignancies. Telomerase Reverse Transcriptase (TERT) is also considered as a potential target for cancer therapeutics. To enable the large-scale screening and identification of potential YY1 targeting drugs, a gastric cancer cell line-based drug screening assay was developed. In a YY1 targeted drug repurpose screen, abacavir sulfate, a nucleoside analog reverse transcriptase inhibitor and known to target TE...

Lania, Vincenzo Rochira, Livio CasariniAbstractGrowth Hormone (GH) deficiency is frequent in HIV-infected patients treated with antiretroviral therapy. We treated GH3 cells with antiretrovirals (nevirapine, ritonavir or abacavir sulfate; 100 pM-1 mM range), after transfection with human growth hormone releasing hormone (GHRH) receptor cDNA. Cells viability, i...

Stability behaviour of antiretroviral drugs and their combinations. 5: Characterization of novel degradation products of abacavir sulfate by mass and nuclear magnetic resonance spectrometry
Publication date: 5 February 2017 Source:Journal of Pharmaceutical and Biomedical Analysis, Volume 134 Author(s): Moolchand Kurmi, Archana Sahu, Saranjit Singh In the present study, degradation behaviour of abacavir sulfate was evaluated in solution and solid stress conditions. Solution state studies resulted in formation of eleven degradation products; of which two were also formed on solid stress. The same were separated by high performance liquid chromatography. They were characterized using liquid chromatography-high resolution mass spectrometry, liquid chromatography-multistage mass spectrometry and hydrogen/deut...

Abacavir/Lamivudine
EPZICOM Tablets contain the following 2 synthetic nucleoside analogues: abacavir sulfate (ZIAGEN, also a component of TRIZIVIR) and lamivudine (also known as EPIVIR or 3TC) with inhibitory activity against HIV-1. EPZICOM Tablets are for oral administration. Each orange, film-coated tablet contains the active ingredients 600 mg of abacavir as abacavir sulfate and 300 mg of lamivudine, and the inactive ingredients magnesium stearate, microcrystalline cellulose, and sodium starch glycolate. The tablets are coated with a film (OPADRY® orange YS-1-13065-A) that is made of FD&C Yellow No. 6, hypromellose, polyethylene gl...

Safety analysis of Ziagen® (abacavir sulfate) in postmarketing surveillance in Japan
ConclusionsDuring the mandatory postmarketing survey of Ziagen, there were no cases of ischemic heart diseases, and the incidence of hypersensitivity was considerably low. These indicated that abacavir can be safely used in Japanese HIV+ population. However, the safety profile of Ziagen should be continued to be monitored through pharmacovigilance. © 2014 The Authors.
