Changes in motor function and weight gain post-treatment in CP kits. The CP kits were randomly divided into 5 groups and received systematic injections of PBS, NAC (2, 5 mg/kg) or G6D-NAC (2, 5 mg/kg). The behavioral scores were assessed at 24, 48, and 96 h post-injection. The suck and swallow (a), head movement (b), and hindleg muscle tone (c) were significantly improved in G6D-NAC2 group at 48 and 96 h post-treatment. Moreover, G6D-NAC 2 mg/kg treatment significantly increased weight gain (d) at 96 h post-treatment. **p < 0.01, ***p < 0.001, G6D-NAC2 vs. PBS, NAC2, and NAC5 groups
