Adenosine amine congener (ADAC) is a selective A1 adenosine receptor agonist, can ameliorate noise- and Cisplatin-induced cochlear injury. Adenosine amine congener also has neuroprotective effects.
IC50&Target
A1 adenosine receptor
体外研究
Adenosine amine congener can reduce oxidative stress in the noise-exposed cochlea, leading to protection of sensory hair cells. Adenosine amine congener also can reduce cisplatin-induced apoptosis in cochlear tissues, particularly in sensory hair cells and strial marginal cells. The mechanisms of otoprotection by Adenosine amine congener include inhibition of glutamate release via presynaptic A1 receptors and inhibition of voltage-gated Ca channels, which can prevent activation of apoptotic and necrotic cell death pathways.

Adenosine amine congener (25-300 μg/kg/day; intraperitoneal injection; daily; for 5 days; male Wistar rats) treatment is most effective in the first 24 hours after noise exposure at doses >50 μg/kg, providing up to 21 dB protection. Adenosine amine congener mitigates noise-induced hearing loss in a dose- and time-dependent manner.
Animal Model:
Male Wistar rats (8-10 weeks old) treated with noise exposure
