ITSA-1

Research use only, not for human use.

A small molecule suppressor that counteracts trichostatin A (TSA)-induced cell cycle arrest.

A small molecule suppressor that counteracts trichostatin A (TSA)-induced cell cycle arrest, histone acetylation and transcriptional activation; also suppresses acetylation of cytoplasmic alpha-tubulin as well as histones induced by hydroxamic acid-based HDAC inhibitors like TSA and SAHA.

ITSA-1 (50 μM; A549 cells) treatment serves to revert the TSA-arrested population to a normal cell cycle distribution. ITSA-1 is also able to effect cell cycle rescue over longer duration.ITSA-1 (50 μM; 5 hours; A549 cells) treatment reduces the number of apoptosis in TSA-treated cells.ITSA-1 (50 μM; 2 hours; A549 and murine ES cells cells) treatment suppresses TSA-induced histone acetylation. Importantly, suppression of acetylation levels is only observable when ITSA1 is added concurrent with or post TSA treatment.ITSA-1 (50 μM; 30 minutes; murine ES cells cells) suppresses TSA-activated transcription in murine ES cells. Cell Cycle AnalysisCell Line:Murine ES cells Concentration:50 μM Incubation Time:Result:Served to revert the TSA-arrested population to a normal cell cycle distribution.Apoptosis Analysis Cell Line:A549 cells Concentration:50 μM Incubation Time:5 hours Result:Reduced the number of apoptosis.Western Blot Analysis Cell Line:A549 and murine ES cells Concentration:50 μM Incubation Time:2 hours Result:Reduced histone acetylation to the baseline level. RT-PCR Cell Line:Murine ES cells Concentration:50 μM Incubation Time:30 minutes Result:Suppressed TSA-activated transcription.

ITSA-1 (0.5 mg/kg; intraperitoneal injection; 3 times/week; for 8 weeks; CBS+/? mice) balances deacetylation activity and suppresses IL-6 and TNF-α expression and thereby attenuated histone acetylationdependent infammatory signaling. Animal Model:CBS+/? miceDosage:0.5 mg/kg Administration:Intraperitoneal injection; 3 times/week; for 8 weeks Result:Balanced deacetylation activity and suppressed IL-6 and TNF-α expression.
