Follicle-stimulating hormone (FSH) action on spermatogenesis: A focus on physiological and therapeutic roles

Background: Human reproduction is regulated by the combined action of the follicle-stimulating hormone (FSH) and the luteinizing hormone (LH) on the gonads. Although FSH is largely used in female reproduction, in particular in women attending assisted reproductive techniques to stimulate multi-follicular growth, its efficacy in men with idiopathic infertility is not clearly demonstrated. Indeed, whether FSH administration improves fertility in patients with hypogonadotropic hypogonadism, the therapeutic benefit in men presenting alterations in sperm production despite normal FSH serum levels is still unclear. In the present review, we evaluate the potential pharmacological benefits of FSH administration in clinical practice. Methods: This is a narrative review, describing the FSH physiological role in spermatogenesis and its potential therapeutic action in men. Results: The FSH role on male fertility is reviewed starting from the physiological control of spermatogenesis, throughout its mechanism of action in Sertoli cells, the genetic regulation of its action on spermatogenesis, until the therapeutic options available to improve sperm production. Conclusion: FSH administration in infertile men has potential benefits, although its action should be considered by evaluating its synergic action with testosterone, and well-controlled, powerful trials are required. Prospective studies and new compounds could be developed in the near future.

Stereochemical control on the Michael addition of chiral 1,3-oxazolidine-2-thiones to N-crotonyl 1,3-oxazolidin-2-ones

Addition of both antipodes of 4-phenyl 1,3-oxazolidine-2-thione to 4-substituted N-crotonyl 1,3-oxazolidin-2-ones furnished Michael addition products. A perfect match occurred when both Michael donor and acceptor possessed the same stereochemistry and a mismatch when they had opposite stereochemistries. The newly created stereochemical center was shown to be governed by the Michael donor and not by the acceptor.

Recent progress on anti-Toxoplasma drugs discovery: Design, synthesis and screening

Toxoplasma gondii severely threaten the health of immunocompromised patients and pregnant women as this parasite can cause several disease, including brain and eye disease. Current treatment for toxoplasmosis commonly have high cytotoxic side effects on host and require long durations ranging from one week to more than one year. The regiments lack efficacy to eradicate T. gondii tissue cysts to cure chromic infection results in the needs for long treatment and relapsing disease. In addition, there has not been approved drugs for treating the pregnant women infected by T. gondii. Moreover, Toxoplasma vaccine researches face a wide variety of challenges. Developing high efficient and low toxic agents against T. gondii is urgent and important. Over the last decade, tremendous progress have been made in identifying and developing novel compounds for the treatment of toxoplasmosis. This review summarized and discussed recent advances between 2009 and 2019 in exploring effective agents against T. gondii from five aspects of drug discovery.

Pharmacology and structural analysis of ligand binding to the orthosteric site of glutamate-like GluD2 receptors

The GluD2 receptor is a fundamental component of postsynaptic sites in Purkinje neurons, and is required for normal cerebellar function. GluD2 and the closely related GluD1 are classified as members of the ionotropic glutamate receptor (iGluR) superfamily on the basis of sequence similarity, but do not bind L-glutamate. The amino acid neurotransmitter D-Ser is a GluD2 receptor ligand, and endogenous D-Ser signaling through GluD2 has recently been shown to regulate endocytosis of a-amino- 3-hydroxy-5-methyl-4-isoxazolepropionic acid-type iGluRs during synaptic plasticity in the cerebellum, such as long-term depression. Here, we investigate the pharmacology of the orthosteric binding site in GluD2 by examining the activity of analogs of D-Ser and GluN1 glycine site competitive antagonists at GluD2 receptors containing the lurcher mutation (GluD2LC), which promotes spontaneous channel activation. We identify several compounds that modulate GluD2LC, including a halogenated alanine analog as well as the kynurenic acid analog 7-chloro- 4-oxo-1H-quinoline-2-carboxylic acid (7-chlorokynurenic acid; 7-CKA). By correlating thermodynamic and structural data for 7-CKA binding to the isolated GluD2 ligand binding domain (GluD2-LBD), we find that binding 7-CKA to GluD2-LBD differs from D-Ser by inducing an intermediate cleft closure of the clamshell-shaped LBD. The GluD2 ligands identified here can potentially serve as a starting point for development of GluD2- selective ligands useful as tools in studies of the signaling role of the GluD2 receptor in the brain.

Arylidenes of Quinolin-2-one scaffold as Erlotinib analogues with activities against leukemia through inhibition of EGFR TK/ STAT-3 pathways

A new series of 6-substiuted-4-(2-(4-substituted-benzylidene)hydrazinyl)quinolin-2(1H)-one derivatives have been designed and synthesized. The structure of the synthesized compounds was proved by 1H NMR, 13C NMR, 2D NMR, mass and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, the most active compounds were further examined against the most sensitive leukemia RPMI-8226 and on healthy cell lines. 6-Chloro-derivative was the most active one; with IC50 = 15.72 ¡À 1.21 and 46.05 ¡À 2.36 muM against RPMI-8226 and normal cell lines, respectively. Also, it showed a remarkable inhibitory activity compared to gefitinib on the EGFR TK mutant, wild and on H-RAS in addition to STAT-3 with IC50 = 695.49 ¡À 21.8, 263.15 ¡À 15.13, 10.61 ¡À 0.27 and 1.753 ¡À 0.81 nM, respectively. Cell cycle analysis of RPMI-8226 cells treated with the 6-chloro-derivative showed cell cycle arrest at G2/M phase (supported by Caspases-3,8, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking studies ROCS analysis and Tanimoto scores supported the results. The study illustrated the effect of several factors on compounds activity.

Triazine as a promising scaffold for its versatile biological behavior

Among all heterocycles, the triazine scaffold occupies a prominent position, possessing a broad range of biological activities. Triazine is found in many potent biologically active molecules with promising biological potential like anti-inflammatory, anti-mycobacterial, anti-viral, anti-cancer etc. which makes it an attractive scaffold for the design and development of new drugs. The wide spectrum of biological activity of this moiety has attracted attention in the field of medicinal chemistry. Due to these biological activities, their structure-activity relationship has generated interest among medicinal chemists and this has culminated in the discovery of several lead molecules. The outstanding development of triazine derivatives in diverse diseases within very short span of time proves its magnitude for medicinal chemistry research. Therefore, these compounds have been synthesized as target structure by many researchers, and were further evaluated for their biological activities. In this review, we have compiled and discussed the biological potential of s-triazine derivatives, which could provide a low-height flying bird’s eye view of the triazine derived compounds to a medicinal chemist, for a comprehensive and target oriented information for the development of clinically viable drugs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 2682-49-7, you can also check out more blogs about2682-49-7
