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.

Lithiation of metallocenes and subsequent addition of the fluorinating agent NFSI gave the fluorinated metallocenes after optimization of the exptl. conditions. All new compounds were comprehensively characterized and the cyclic voltammograms of fluoro- and 1,1′-difluoroferrocene were recorded and compared to other mono- and dihalogenated ferrocenes. Half-wave potentials of +106 mV and +220 mV vs. FcH0/+ were obtained for monofluorinated species and difluorinated ferrocene, resp. Both values are remarkably low compared to the other halogenated ferrocenes (Cl, Br, and I).
