6'-GNTI dihydrochloride 是一种κ-阿片受体（KOR）激动剂，它偏向于激活 G 蛋白介导的信号传导，而不是β-阿司匹林2的募集。6'-GNTI dihydrochloride 只能激活纹状体神经元中的 Akt 通路。

Eprociclovir Na is the salt form of Eprociclovir, also known as A-5021, a new acyclovir analogue and a potent inhibitor of EHV1 replication and may have potential for the treatment and or prophylaxis of infections with this virus. Eprociclovir possess potent anti-herpetic activity against most human herpesviruses. A-5021 proved to be about 15-fold more potent than acyclovir in inhibiting viral replication. Eprociclovir inhibits murine herpetic keratitis. A-5021 eyedrops, which are easily applied onto the affected cornea, ameliorated clinical scores and suppressed virus growth. Eprociclovir is a promising alternative treatment of herpetic keratitis.

GNTI TFA is a selective kappa opioid receptor antagonist.
