Lowe, Robert A. published the artcileSynthesis and evaluation of the performance of a small molecule library based on diverse tropane-related scaffolds, Recommanded Product: trimethyloxosulphonium chloride, the publication is Bioorganic & Medicinal Chemistry (2020), 28(9), 115442, database is CAplus and MEDLINE.

A unified synthetic approach was developed that enabled the synthesis of diverse tropane-related scaffolds. The key intermediates that were exploited were cycloadducts formed by reaction between 3-hydroxypyridinium salts and vinyl sulfones or sulfonamides. The diverse tropane-related scaffolds were formed by addition of substituents to, cyclization reactions of, and fusion of addnl. ring(s) to the key bicyclic intermediates. A set of 53 screening compounds was designed, synthesized and evaluated in order to determine the biol. relevance of the scaffolds accessible using the synthetic approach. Two inhibitors of Hedgehog signalling, and four compounds with weak activity against the parasite P. falciparum, were discovered. Three of the active compounds may be considered to be indotropane or pyrrotropane pseudo natural products in which a tropane is fused with a fragment from another natural product class. It was concluded that the unified synthetic approach had yielded diverse scaffolds suitable for the design of performance-diverse screening libraries.

Sattin, Sara published the artcileActivation of Hsp90 Enzymatic Activity and Conformational Dynamics through Rationally Designed Allosteric Ligands, Category: chlorides-buliding-blocks, the publication is Chemistry – A European Journal (2015), 21(39), 13598-13608, database is CAplus and MEDLINE.

Hsp90 is a mol. chaperone of pivotal importance for multiple cell pathways. ATP-regulated internal dynamics are critical for its function and current pharmacol. approaches block the chaperone with ATP-competitive inhibitors. Herein, a general approach to perturb Hsp90 through design of new allosteric ligands aimed at modulating its functional dynamics is proposed. Based on the characterization of a first set of 2-phenylbenzofurans showing stimulatory effects on Hsp90 ATPase and conformational dynamics, new ligands were developed that activate Hsp90 by targeting an allosteric site, located 65 Å from the active site. Specifically, anal. of protein responses to first-generation activators was exploited to guide the design of novel derivatives with improved ability to stimulate ATP hydrolysis. The mols.’ effects on Hsp90 enzymic, conformational, co-chaperone and client-binding properties were characterized through biochem., biophys. and cellular approaches. These designed probes act as allosteric activators of the chaperone and affect the viability of cancer cell lines for which proper functioning of Hsp90 is necessary.

A series of novel 12N-substituted matrinane derivatives were synthesized and evaluated for their activities against coxsackievirus type B3 (CVB3) taking compound I as the lead. SAR anal. indicated that the introduction of a suitable heteroaromatic ring on the 12N-atom might be beneficial for the activity. Among them, compound II exhibited the highest potency against all CVB serotypes as well as CVA16 with IC₅₀ values ranging from 2.02 μM to 7.41 μM, indicating a broad-spectrum anti-coxsackieviruse effect. Furthermore, compound II demonstrated a good safety profile in vivo. Thus, we consider 12N-substituted matrinanes to be a promising family of anti-coxsackievirus agents, and compound II to be a promising drug candidate in the treatment of various diseases related to coxsackievirus infection.

Yanagi, Tomoyuki published the artcileAsymmetric systematic synthesis, structures, and (chir)optical properties of a series of dihetero[8]helicenes, Safety of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Chemical Science (2021), 12(8), 2784-2793, database is CAplus and MEDLINE.

A series of dihetero[8]helicenes (P)/(M)/(rac)-I (R = O, S, NH, SO₂) have been systematically synthesized in enantiomerically enriched forms by utilizing the characteristic transformations of the organosulfur functionality. The synthetic route begins with assembling a ternaphthyl II common synthetic intermediate from 2-naphthol and 2,7-bis(phenethylsulfinyl)naphthalene through an extended Pummerer reaction followed by facile multi-gram-scale resolution The subsequent cyclization reactions into dioxa- and dithia[8]helicenes (P)/(M)/(rac)-I take place with excellent axial-to-helical chirality conversion. Dithia[8]helicenes (P)/(M)/(rac)-III are further transformed into the nitrogen (P)/(M)/(rac)-I and the carbon analogs (P)/(M)/(rac)-IV and (P)/(M)/(rac)-V by replacing the two endocyclic sulfur atoms via S_NAr-based skeletal reconstruction. The efficient systematic synthesis has enabled comprehensive evaluation of phys. properties, which has clarified the effect of the endocyclic atoms on their structures and (chir)optical properties as well as the unexpected conformational stability of the common helical framework.
