The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《A New Approach To Predict the Biological Activity of Molecules Based on Similarity of Their Interaction Fields and the logP and logD Values: Application to Auxins》. Authors are Bertosa, Branimir; Kojic-Prodic, Biserka; Wade, Rebecca C.; Ramek, Michael; Piperaki, Stavroula; Tsantili-Kakoulidou, Anna; Tomic, Sanja.The article about the compound:2-(7-Bromo-1H-indol-3-yl)acetic acidcas:63352-97-6,SMILESS:O=C(O)CC1=CNC2=C1C=CC=C2Br).Related Products of 63352-97-6. Through the article, more information about this compound (cas:63352-97-6) is conveyed.

The activity of a biol. compound is dependent both on specific binding to a target receptor and its ADME (Absorption, Distribution, Metabolism, Excretion) properties. A challenge to predict biol. activity is to consider both contributions simultaneously in deriving quant. models. We present a novel approach to derive QSAR models combining similarity anal. of mol. interaction fields (MIFs) with prediction of logP and/or logD. This new classification method is applied to a set of about 100 compounds related to the auxin plant hormone. The classification based on similarity of their interaction fields is more successful for the indole than the phenoxy compounds The classification of the phenoxy compounds is however improved by taking into account the influence of the logP and/or the logD values on biol. activity. With the new combined method, the majority (8 out of 10) of the previously misclassified derivatives of phenoxy acetic acid are classified in accord with their bioassays. The recently determined crystal structure of the auxin-binding protein 1 (ABP1) enabled validation of our approach. The results of docking a few auxin related compounds with different biol. activity to ABP1 correlate well with the classification based on similarity of MIFs only. Biol. activity is, however, better predicted by a combined similarity of MIFs + logP/logD approach.

Mcl-1 has recently emerged as an attractive target to expand the armamentarium in the war on cancer. Using structure-based design, 3-carboxy-substituted 1,2,3,4-tetrahydroquinolines were developed as a new chemotype to inhibit the Mcl-1 oncoprotein. The most potent compound inhibited Mcl-1 with a Ki of 120 nM, as determined by a fluorescence polarization competition assay. Direct binding was confirmed by 2D 1H-15N HSQC NMR spectroscopy with 15N-Mcl-1, which indicated that interactions with R263 and T266, and occupation of the p2 pocket are likely responsible for the potent binding affinity. The short and facile synthetic chem. to access target mols. is expected to mediate lead optimization.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Reactions of haloferrocenes. III. Reaction of haloferrocenes with copper(I) benzenethiolate, thiocyanate, acetate, and benzoate.Recommanded Product: Bromoferrocene.

Iodoferrocene reacted with copper(I) benzenethiolate in boiling pyridine to give ferrocenyl Ph sulfide in a quant. yield. The reaction of iodoferrocene with copper(I) thiocyanate gave diferrocenyl disulfide. The behavior of copper(I) acetate and benzoate toward haloferrocene was different from those of the other copper(I) salts: reactions in boiling pyridine gave the corresponding ferrocenyl ester, together with a small quantity of ferrocene, while the reaction in boiling toluene produced biferrocenyl as the main product.
