Pseudomonas aeruginosa DgcvP2 mutant 200 mg/L 24 hours Cysteamine inhibited glycine utilization by P. aeruginosa DgcvP2 mutant PMC8494450
Pseudomonas aeruginosa PAO1 200 mg/L 24 hours Cysteamine inhibited glycine utilization by P. aeruginosa PAO1 PMC8494450
Gilthead sea bream (Sparus aurata) myocytes 200 µM 4 days To evaluate cell viability and GH/IGF axis-related gene expression. Results showed that CSH treatment increased cell viability and upregulated mRNA levels of ghr1, igf-1b, igf-2, and igf-1rb compared to the control group. PMC10400459
Calu-3 cells 500-125 μM 48 hours To assess the impact of cysteamine and cystamine on SARS-CoV-2 replication. Results demonstrated that both compounds significantly reduced viral production. PMC8750154
THP-1 cells 800 µM 48 hours Restricted intracellular replication compared to the untreated control PMC9866335
THP-1 cells 400 µM 48 hours Restricted intracellular replication compared to the untreated control PMC9866335
Burkholderia cepacia complex (BCC) clinical isolates and type strains 128 μg/ml 48 hours To assess the utility of cysteamine as an adjunct antibiotic therapy against BCC in vitro, results showed that cysteamine potentiated the activity of tobramycin, ciprofloxacin, and trimethoprim-sulfamethoxazole, reversing resistance in some strains. PMC5038277
Peripheral blood mononuclear cells (PBMCs) 50-400 µM 6 hours and 24 hours To evaluate the immunomodulatory effects of cysteamine on Th1 and Tc1 cell responses. Results showed that cysteamine at 400 µM significantly reduced PPD- and SEB-induced Th1 and Tc1 responses. PMC11550979
Vero E6 cells 500-31.25 μM 72 hours To evaluate the effect of cysteamine and cystamine on SARS-CoV-2-induced cytopathic effects (CPE). Results showed that both compounds significantly reduced SARS-CoV-2-induced CPE in a dose-dependent manner. PMC8750154

Gilthead sea bream (Sparus aurata) Fingerlings (1.8 ± 0.03 g) and juveniles (14.46 ± 0.68 g) Oral 1.65 g/kg or 3.3 g/kg 9 and 18 weeks To investigate the effects of CSH on growth performance and the GH/IGF-1 axis. Results showed that CSH-1.65 improved growth performance by 16% and 26.7% after 9 and 18 weeks, respectively, while CSH-3.3 improved 32.3% after 18 weeks. CSH reduced plasma GH levels after 18 weeks and increased IGF-1 levels after 9 and 18 weeks. PMC10400459

Results showed that CSH-1.65 improved growth performance by 16% and 26.7% after 9 and 18 weeks, respectively, while CSH-3.3 improved 32.3% after 18 weeks. CSH reduced plasma GH levels after 18 weeks and increased IGF-1 levels after 9 and 18 weeks. PMC10400459
Mice Heterozygous reeler mice (HRM) Through drinking water 150 mg/kg/day 30 days To evaluate the potential of cysteamine to improve the deficits in GAD67 expression and cognitive function in HRM. Results showed that cysteamine significantly ameliorated the decreases in GAD67, mature BDNF and full-length TrkB protein levels in frontal cortex and hippocampus of HRM. Additionally, cysteamine improved Y-maze spatial recognition in HRM to the level of wide-type controls and improved PPI in both wild-type and HRM. PMC3248979

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
Protocol 1
Protocol 2
The prepared working fluid is recommended to be prepared now and used up as soon as possible in a short period of time. The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
