Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to assess the safety, tolerability, and pharmacokinetic profiles of Y-3 in healthy adult volunteers in the United States. The main questions it aims to answer are:

* What the pharmacokinetic profiles of single ascending doses of Y-3 (40 mg and 60 mg) in the US healthy adult volunteers?
* If drug Y-3 (40mg and 60 mg) is safe and tolerate in the US healthy adult volunteers.

Researchers will compare drug Y-3 (40 mg and 60 mg) to a placebo (a look-alike substance that contains no drug) to see what the pharmacokinetic profiles of single ascending doses of Y-3 (40 mg and 60 mg) in the US healthy adult volunteers and if drug Y-3 (40mg and 60 mg) is safe and tolerate in the US healthy adult volunteers.

Participants will:

* Take drug Y-3 (40 mg) or Y-3 (60 mg) or a placebo only once.
* Answer questions regarding your medical history.
* Comply with the study procedures and requests.
* Complete all tests and collections of PK Sampling.
* Must not have any special dietary requirements and be able to consume the food (low-fat) provided by Tranquil Clinical Research during your 4-night stay.
* Must avoid excessive ( \> 8 cups per day) caffeine consumption (i.e. coffee or tea) during your time in the study.
* Must not consume any food or beverage rich in grapefruit, papaya, or mango during your time in the study.
* Must not take any other medications, including traditional Chinese medicines and herbal medicines, during your time in the study.
* Must avoid sexual activity or use non-drug contraceptive measures (i.e. condoms) during your time in the study.
* Female participants must not become pregnant while in the study.
* Must not receive any vaccinations during your time in the study.
* Must not donate blood for purposes outside of study procedures during your time in the study.
* Must not drink alcohol during your time in the study.
* Must not smoke during your time in the study.
* Inform your Study Doctor if you no longer wish to participate in the study.

Y-3 for injection (Y-3)

The investigational drug (Y-3) consists of two parts: Y-3 for injection (lyophilized powder) (20 mg)and Solvent for Y-3 for injection (concentrated solution)(3ml (containing 0.6 g propylene glycol)).

Subjects will receive Y-3 or placebo on the morning of the dosing day. Drinking water is prohibited from 1 hour before administration until the end of dosing, and subjects may have meals 4 hours after administration.

Using a sterile syringe, withdraw dedicated solution into the lyophilized powder vial of Y-3 or placebo. Shake the vial manually until the powder is dissolved. Once completely dissolved, use a sterile syringe to transfer the solution into the infusion bottle (normal saline) and gently mix by swirling. The intravenous infusion volume is 250 ml, and infusion time is 60 min ± 10 min. The storage time of the reconstituted drug product or placebo should not exceed 4 hours at room temperature or 24 hours at refrigerated temperature prior to initiation of administration.
