Targeted Sensitization of Leukemic T-cells to Anticancer Drugs by SIRT1 Agonist SRT-1720.
(PubMed, Anticancer Res)
- "SRT-1720 induces oxidative stress and apoptosis in leukemic lymphocytes through SIRT1-independent pathway(s). In contrast, it enhances antioxidant defense in normal lymphocytes through a SIRT1-dependent pathway. These findings highlight the potential of SRT-1720 as an adjuvant to chemotherapy in T-ALL, particularly in drug combinations demonstrating strong synergism, which may allow dose reduction and decreased toxicity."

SIRT1: An Emerging Role in Regulated Cell Death in Ischemic Stroke.
(PubMed, CNS Neurol Disord Drug Targets)
- "Moreover, SIRT1 modulators, including resveratrol, SRT1720, EX-527, and Sirtinol, have demonstrated neuroprotective effects in preclinical and clinical trials. Thus, future research should aim to overcome these obstacles and develop novel SIRT1 modulators with better clinical translation potential, ultimately improving IS treatment outcomes. This review further explores the therapeutic implications of SIRT1 modulation in IS treatment and highlights the urgent need for more clinical validation to support its broader application."

Cigarette smoke exposure triggers dendritic cell-derived exosome-mediated Th17 and Treg polarization through an autophagy- and necroptosis-associated SIRT1-dependent mechanism in vitro.
(PubMed, Front Immunol)
- "CSE exposure induces an imbalance in Th17/Treg polarization through a process mediated by DCexos that entails reduced SIRT1 expression, increased necroptosis, and dysregulated autophagy. SIRT1 activation by SRT1720 can attenuate these effects by restoring immune balance and modulating cell death and survival pathways in DCs under CSE exposure."

Quercetin ameliorates SIRT1-mediated oxidative stress and inflammation to attenuate ciliary muscle remodeling in experimental myopia.
(PubMed, Biochem Pharmacol)
- "To this end, a randomized controlled trial was conducted using negative lens-induced myopic (LIM) guinea pig models for durations of 4 weeks and 6 weeks, with subjects administered quercetin (QUE) or SRT1720...Furthermore, Western blotting revealed upregulated SIRT1, NRF2, and TIMP-2 expression but downregulated KEAP1 and MMP-2 expression in the intervention groups, and ELISA revealed decreased inflammatory responses. In conclusion,quercetin could play a protective role by increasing the expression of SIRT1, which in turn alleviated KEAP1/NRF2-induced oxidative stress and mitigated NF-κB-driven inflammatory damage, thereby ameliorating ciliary muscle remodeling and potentially delaying the progression of myopia."

Defective mitophagy of CD4+T cells in ITP via NAD+/SIRT1 reduction
(ASH 2025)
- "Nicotinamide riboside (NR) and a SIRT1 agonist (SRT1720) were administered to ITPCD4+ T cells in vitro to reveal the role of the NAD+/SIRT1 axis in mitophagy deficiency. GSEA revealed that the expression oftype I interferon in ITP CD4+ T cells and the pathways positively regulated by type 1 interferon weresignificantly upregulated, suggesting that mitophagy deficiency may promote the production of type Iinterferons by CD4+ T cells in ITP, thereby participating in the immune imbalance in ITP.ConclusionDefects in the NAD+/SIRT1 axis lead to mitophagy deficiency in ITP CD4+ T cells, resulting in an immuneimbalance in ITP. Targeted correction of the NAD+/SIRT1 axis can regulate CD4+ T-cell differentiationthrough the correction of mitophagy in ITP CD4+ T cells, providing new therapeutic ideas and targets forthe clinical treatment of ITP."

(PubMed, CNS Neurosci Ther)
- "The AMPK/SIRT1/PGC-1α pathway represents a cornerstone target at the intersection of metabolism, aging, and disease. Current therapeutic strategies-including pharmacological activators (e.g., metformin, SRT1720), natural compounds (e.g., resveratrol), lifestyle interventions (e.g., exercise, caloric restriction), and emerging technologies (e.g., gene editing, exosomal miRNAs)-offer multidimensional avenues for intervention. Future research must prioritize elucidating tissue-specific regulatory mechanisms, such as AMPK isoform diversity and PGC-1α interactome dynamics, to enable precision therapeutics and successful clinical translation for a range of complex disorders."

Thyroid hormone deficiency worsens outcomes in vaccinia virus infection.
(PubMed, J Virol)
- "Further highlighting the link between thyroid hormones and immune defense, we show that SRT1720, a Sirtuin 1 activator, reduces thyroid hormone levels and also worsens vaccinia infection when administered to euthyroid mice...Hypothyroidism also impairs the amplification of splenic lymphocytes, which play a key role in defense against viral infection. Furthermore, vaccinia virus infection reduces thyroid hormone levels in euthyroid mice, a phenomenon named "non-thyroidal illness syndrome" that often occurs in septic patients, suggesting that, in the context of viral pulmonary infections, thyroid hormone replacement might be a useful therapeutic option."

SIRT1 inhibits ferroptosis of granulosa cells in polycystic ovarian syndrome.
(PubMed, Int J Biol Macromol)
- "Functional assays revealed that SIRT1 overexpression or pharmacological activation by SRT1720 significantly decreased lipid peroxidation and reactive oxygen species levels, thereby alleviating ferroptosis (p < 0.05). Mechanistically, co-immunoprecipitation indicated that SIRT1 interacted with Nrf2, and molecular docking suggested potential SIRT1-binding compounds. Collectively, these findings indicate that SIRT1 suppresses ferroptosis in granulosa cells via Nrf2 deacetylation, providing new insight into PCOS pathogenesis and suggesting SIRT1 as a potential therapeutic target."

(ASH 2024)
- "Furthermore, EX527, a Sirt-1 inhibitor and SRT1720, a Sirt-1 agonist, as well as lentiviral interference of Sirt-1 in Tregs were used to verify the target of anti-CD38 therapy. In both Group B and C, significantly ameliorated thrombocytopenia, increasedproportion of splenic Tregs, down-regulated Sirt-1 in Foxp3 positive frozen sections, and restoration of anti-/pro-inflammatory cytokine profiles was demonstrated, compared with Group A. Conclusion : In summary, CD38 monoclonal antibody potentially reprograms the immunosuppressive function of Tregs by inhibiting Sirt-1, which provides a novel target for the management of ITP. This study suggested versatile mechanisms of anti-CD38 therapy in autoimmune disorders and rationalized its long-term efficacy in patients with ITP."

- " Mouse 3T3-L1 preadipocytes were treated during differentiation with either rosiglitazone (RGZ), the SIRT1 activator SRT1720, or the SIRT1 inhibitor EX527. These findings demonstrate that Lipin-1 interacts with the SIRT1-PPARγ-SRSF10 axis in adipocytes and contributes to the acquisition of beige/brown-like characteristics in WAT. This regulatory pathway may represent a potential target for improving lipid metabolism and metabolic health."
