Development of Sensitive and Specific Analysis of Vildagliptin in Pharmaceutical Formulation by Gas Chromatography-Mass Spectrometry.

Journal of analytical methods in chemistry

Uçaktürk E.
PMID: 26682085
J Anal Methods Chem. 2015;2015:707414. doi: 10.1155/2015/707414. Epub 2015 Nov 22.

A sensitive and selective gas chromatography-mass spectrometry (GC-MS) method was developed and fully validated for the determination of vildagliptin (VIL) in pharmaceutical formulation. Prior to GC-MS analysis, VIL was efficiently derivatized with MSTFA/NH4I/β-mercaptoethanol at 60°C for 30 min. The...

Our aim was to evaluate the independent and associated effects of nandrolone decanoate (DECA) and resistance exercise (REx) on central and peripheral hormones and neuropeptides related to energy balance in male rats. The experimental protocol was performed for eight...

Assessment of testicular steroidogenic enzymes expression in experimental animal model following withdrawal of nandrolone decanoate.

Journal of animal science and technology

J Anim Sci Technol. 2021 Nov;63(6):1247-1264. doi: 10.5187/jast.2021.e102. Epub 2021 Nov 30.

Anabolic steroids are frequently used to increase the growth rate of meat-producing animals. Exposure to an anabolic-androgenic steroid, nandrolone decanoate (ND), is associated with expressional reduction of testicular steroidogenic enzymes. However, the effect of withdrawal of ND exposure on...

Effects of androgen and progestin on the proliferation and differentiation of osteoblasts.

Experimental and therapeutic medicine

Exp Ther Med. 2018 Dec;16(6):4722-4728. doi: 10.3892/etm.2018.6772. Epub 2018 Sep 19.

Osteoporosis is liable to affect patients with gonadal hormone deficiency, and a supplement of androgens may be used to increase bone density of patients with osteoporosis. Since the androgens currently used may cause severe side effects, it is useful...

Anabolic-androgenic steroids impair mitochondrial function and redox status in the heart and liver of mice.

Steroids

Steroids. 2021 Aug;172:108861. doi: 10.1016/j.steroids.2021.108861. Epub 2021 May 11.

Supraphysiological doses of anabolic-androgenic steroids (AAS) may cause long-term functional abnormalities, particularly in the heart and liver, which may only represent the later-stage of the cumulative damage caused by dysfunctional organelles. We investigated whether mid-term supraphysiological doses of Testosterone...

OXER1 and RACK1-associated pathway: a promising drug target for breast cancer progression.

Oncogenesis
