TT-301
TT-301 is a small-molecule immunomodulator capable of penetrating the blood-brain barrier. TT-301 exerts neuroprotective effects by binding to IL-1β, downregulating STAT3 expression, and modulating the JAK-STAT signaling pathway, thereby inhibiting microglial activation and the release of proinflammatory mediators, and alleviating neuroinflammation and brain edema. TT-301 is used in research on traumatic brain injury, intracerebral hemorrhage, subarachnoid hemorrhage, muscle wasting and atrophy, and periodontal disease.

In Vitro
TT-301 (1-60 μM; 90 min) hydrochloride inhibits lipopolysaccharide-induced production of pro-inflammatory cytokines and chemokines in BV2 microglia in a dose-dependent manner without reducing cell viability[2].
TT-301 (1-60 μM; 90 min) hydrochloride inhibits lipopolysaccharide-induced production of pro-inflammatory cytokines in EOC20 microglia in a dose-dependent manner without reducing cell viability[2].
TT-301 hydrochloride exhibits effective binding affinity to human IL-1β protein in computer-simulated molecular docking experiments, with a binding energy of -7.8 kcal/mol[1].

In Vivo
TT-301 (1 mg/kg; i.p.; twice daily; for 5 consecutive days) hydrochloride alleviates cerebral edema and improves vestibular motor function in C57BL/6J mice, without affecting hematoma volume[2].
TT-301 (5 mg/kg; i.p.; once every 12 h; for 7 days after subarachnoid hemorrhage) hydrochloride improves survival rate, ameliorates functional outcomes, and attenuates neuronal injury in female C57BL/6 J mice[5].
TT-301 (5 mg/kg; i.p.; once every 12 h; for 7 days after subarachnoid hemorrhage) hydrochloride induces sustained functional improvement, reduces microgliosis, and modulates cerebral inflammatory cytokine levels in male C57BL/6 J mice[5].
