Detection and quantification of the metabolite Ac-Tβ 1-14 in in vitro experiments and urine of rats treated with Ac-Tβ4: A potential biomarker of Ac-Tβ4 for doping tests. Drug Test Anal 2023; 15:1454-1467. [PMID: 37515313 DOI: 10.1002/dta.3552] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/04/2023] [Accepted: 07/05/2023] [Indexed: 07/30/2023]
Abstract
Thymosin β4 (Tβ4) was reported to exert various beneficial bioactivities such as tissue repair, anti-inflammation, and reduced scar formation, and it is listed on the prohibited substances in sports by the World Anti-Doping Agency. However, no metabolism studies of Tβ4 were reported yet. Previously, our lab reported in in vitro experiment that a total of 13 metabolites were found by using multiple enzymes, and six metabolites (Ac-Tβ31-43 , Ac-Tβ17-43 , Ac-Tβ1-11 , Ac-Tβ1-14 , Ac-Tβ1-15 , and Ac-Tβ1-17 ) were confirmed by comparing with the synthetic standards. This study was aimed at identifying new metabolites of Tβ4 leucine aminopeptidase (LAP), human kidney microsomes (HKM), cultured huvec cells, and rats after administration of Tβ4 protein to develop biomarkers for detecting doping drugs in sports. A method for detecting and quantifying Ac-Tβ1-14 was developed and validated using Q-Exactive orbitrap mass spectrometry. The limit of detection (LOD) and limit of quantification (LOQ) of the Ac-Tβ1-14 were 0.19 and 0.58 ng/mL, respectively, and showed a good linearity (r2 = 0.9998). As a result, among the six metabolites above, Ac-Tβ1-14 , as a common metabolite, was found in LAP, HKM, huvec cells exposed to Tβ4, and the urine of rats intraperitoneally treated with 20-mg/kg Tβ4. And the metabolite Ac-Tβ1-14 was quantitatively determined by 48 h in rats, with the highest concentration occurring between 0 and 6 h. Ac-Tβ1-14 was not detected in non-treated control groups, including human blank urine. These results suggest that Ac-Tβ1-14 in urine is a potential biomarker for screening the parent Tβ4 in doping tests.

Wu X, Zhang F, Yu M, Wang H. Review of the Chinese Landscape in Phase I Clinical Trials for Noncancer Innovative Drugs Over 2015 to 2020. Clin Pharmacol Drug Dev 2022; 11:903-909. [PMID: 35711154 DOI: 10.1002/cpdd.1131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 05/30/2022] [Indexed: 11/05/2022]
Abstract
In recent years, the research and development (R&D) of innovative drugs in China has been dramatically accelerated. And the early clinical study is crucial for drug R&D. However, little is known involving the change of phase I trials for noncancer drugs. We retrieved the data of phase I clinical trials for noncancer innovative drugs on the Registration and Information Disclosure Platform for Drug Clinical Studies on the Center for Drug Evaluation. The number of clinical trials proliferating in recent years and the average annual growth rates of chemical and biological drugs were 55.5% and 42.1%, respectively. Most trials were distributed in Beijing, Shanghai, and other developed coastal cities. Moreover, the clinical trials of innovative drugs in China were focused on the digestive and endocrine systems, whereas the pediatric and orphan drugs were scarce. Based on the data assessment, this work provided comprehensive analysis and suggestions about Chinese drug R&D. Significant advancement has been made in mainland China with the implementation of available policies and the emergence of advanced technologies. Though shortcomings, including uneven geographic distribution and lack of pediatric and orphan drugs, still exist, we believe progress will continue to be made in mainland China.

Abstract
Thymosin β4 (Tβ4) is a multifunctional and widely distributed peptide that plays a pivotal role in several physiological and pathological processes in the body, namely, increasing angiogenesis and proliferation and inhibiting apoptosis and inflammation. Moreover, Tβ4 is effectively utilized for several indications in animal experiments or clinical trials, such as myocardial infarction and myocardial ischemia-reperfusion injury, xerophthalmia, liver and renal fibrosis, ulcerative colitis and colon cancer, and skin trauma. Recent studies have reported the potential application of Tβ4 and its underlying mechanisms. The present study reveals the progress regarding functions and applications of Tβ4.
