Small molecule follicle-stimulating hormone receptor agonists and antagonists

The follicle-stimulating hormone receptor (FSHR) has been targeted therapeutically for decades, due to its pivotal role in reproduction. To date, only purified and recombinant/biosimilar FSH have been used to target FSHR in assisted reproduction, with the exception of corifollitropin alfa; a modified gonadotropin in which the FSH beta subunit is joined to the C-terminal peptide of the human choriogonadotropin beta subunit, to extend serum half-life. Assisted reproduction protocols usually entail the trauma of multiple injections of FSH to initiate and promote folliculogenesis, which has prompted the development of a number of orally-available low molecular weight (LMW) chemical scaffolds targeting the FSHR. Furthermore, the recently documented roles of the FSHR in diverse extragonadal tissues, including cancer, fat metabolism, and bone density regulation, has highlighted the potential utility of LMW modulators of FSHR activity. Despite these chemical scaffolds encompassing a spectrum of in vitro and in vivo activities and pharmacological profiles, none have yet reached the clinic. In this review we discuss the major chemical classes of LMW molecules targeting the FSHR, and document their activity profiles and current status of development, in addition to discussing potential clinical applications.

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.HPLC of Formula: C3H5NOS, you can also check out more blogs about2682-49-7

2-(2-arylidenehydrazinyl) thiazol-4(5H)-ones as epidermal growth factor receptor inhibitors: A combined quantitative structure activity relationship and pharmacophore study

2-(2-Arylidenehydrazinyl) thiazol-4(5H)-ones having epidermal growth factor receptor (EGFR) inhibitory activity were subjected to quantitative structure activity relationship (QSAR) (2 and 3 dimensional) analysis and pharmacophore study in the present work. The best 2 dimensional (2D) QSAR model had r2 (squared correlation coefficient), q2 (cross validated correlation coefficient) and pred_r2 (predictive correlation coefficient) values of 0.8630, 0.7652 and 0.9533 respectively with Partial least square regression (PLSR) analysis. This model showed that count of number of nitrogen atoms separated from oxygen atom by four bonds (T_N_O_4) and RadiusOfGyration (size descriptor) descriptors contribute positively and count of number of any atoms separated from carbon atom by four bonds (T_T_C_4) contributes inversely to the biological activity. The k-nearest neighbor (kNN) method produced a significant 3 dimensional (3D) QSAR model exhibiting q2 and pred_r2 values of 0.6615 and 0.8833 respectively. PLSR gave a significant 3D QSAR model having r2, q2 and pred_r2 values of 0.8449, 0.7816 and 0.7834 respectively. Both 3D QSAR models depict the need of less bulky substituents at R2 position while PLSR 3D QSAR model also portrays the need of more bulky substituent at R4 position. The identified common pharmacophore features are one aromatic (AroC) and three hydrogen bond acceptors (HAc) obtained from Molsign and Pharmagist approaches. The present work may be useful for further lead optimization and designing of potent anticancer agents.

Neutrophil-mediated vascular barrier injury: Role of neutrophil extracellular traps

Neutrophils play an essential role in host defense against infection or injury. While neutrophil activation is necessary for pathogen clearance and tissue repair, a hyperactive response can lead to tissue damage and microcirculatory disorders, a process involving complex neutrophil?endothelium cross talk. This review highlights recent research findings about neutrophil-mediated signaling and structural changes, including those induced by neutrophil extracellular traps, which ultimately lead to vascular barrier injury.

Phosphine Organocatalysis

The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a phosphine to an electrophilic starting material, producing a reactive zwitterionic intermediate, generally under mild conditions. In this Review, we classify nucleophilic phosphine catalysis reactions in terms of their electrophilic components. In the majority of cases, these electrophiles possess carbon-carbon multiple bonds: alkenes (section 2), allenes (section 3), alkynes (section 4), and Morita-Baylis-Hillman (MBH) alcohol derivatives (MBHADs; section 5). Within each of these sections, the reactions are compiled based on the nature of the second starting material – nucleophiles, dinucleophiles, electrophiles, and electrophile-nucleophiles. Nucleophilic phosphine catalysis reactions that occur via the initial addition to starting materials that do not possess carbon-carbon multiple bonds are collated in section 6. Although not catalytic in the phosphine, the formation of ylides through the nucleophilic addition of phosphines to carbon-carbon multiple bond-containing compounds is intimately related to the catalysis and is discussed in section 7. Finally, section 8 compiles miscellaneous topics, including annulations of the Hueisgen zwitterion, phosphine-mediated reductions, iminophosphorane organocatalysis, and catalytic variants of classical phosphine oxide-generating reactions.

Organocatalytic Cyclization of COS and Propargylic Derivatives to Value-Added Heterocyclic Compounds

The organocatalytic cyclization of propargylic amines/amides with carbonyl sulfide (COS) was firstly achieved by employing COS adducts of Lewis base (LB) as organocatalysts, affording various functionalized 1,3-thiazolidine-2-ones, and 1,3-thiazolidine-2,4-diones derivatives in a highly chemo- and stereoselective manner. The isotope labeling and stoichiometric experiments suggested the LB-COS adducts preferentially mediated basic ionic pair mechanism. Furthermore, the practical application of this methodology was highlighted by the highly efficient synthesis of rosiglitazone using COS as sulfur source.

Diastereoselective additions of titanium enolates from N-glycolyl thiazolidinethiones to acetals

The stereochemical outcome of the Lewis acid-mediated glycolate addition of the titanium enolates from protected N-hydroxyacetyl-4-isopropyl-1,3- thiazolidine-2-thiones to dimethyl and dibenzyl acetals depends on the hydroxyl protecting group. Particularly, the pivaloyl protected glycolate derivative provides the reluctant anti adducts in high yields and diastereomeric ratios, which can be isolated and further converted in enantiomerically pure form to beta-methoxy or beta-benzyloxy alpha-pivaloyloxy carbonyl fragments in a straightforward manner.
