During a program directed at selective NK1 receptor antagonists, we serendipitously discovered an NK1 receptor ligand with addnl. affinity for the NK3 receptor. Recognising an opportunity for a drug discovery program aiming for dual NK1/NK3 receptor antagonists, we prepared a series of analogs from a novel, versatile building block. From this series emerged compounds with high and balanced affinities for the NK1 and the NK3 receptors. Typical representatives of this series were active in the gerbil foot tapping assay after oral administration.

Reference of Aluminum(III) sulfate xhydrate. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Study on the structure and composition of anodic oxide films of aluminum. Author is Xu, Tao; Zhao, Jiazheng; Cheng, Jianming; Dang, Hongxin.

The structure and composition of the porous anodic oxide films of Al (abbreviated AOFAl) formed in oxalic acid (I) and H2SO4 (II) solutions, resp., were studied by TEM, IR and TGA. The porous anodic oxide films consist of a large number of hexagonal cells with an irregularly round pore in the center of each cell which penetrates vertically from surface to bottom, while a barrier layer under the film directly contacts with an Al substrate in a scallop shape. The content of Al2(C2O4)3 and Al2(SO4)3 in AOFAl (I) and (II) are ∼4.9% and ∼14.2%, resp.; ∼3.5% H2O of crystallization of Al2(SO4)3.xH2O which can be evolved at rather low temperature (∼85°) enriches between the cells and under the barrier layer of AOFAl (II); after irradiation by the electron beam of TEM the H2O of crystallization is removed and voids are formed.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Configuration of the camphoric acids》. Authors are Walker, James; Wood, John K..The article about the compound:(1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acidcas:560-09-8,SMILESS:CC1(C)[C@@H](CC[C@]1(C)C(O)=O)C(O)=O).Reference of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid. Through the article, more information about this compound (cas:560-09-8) is conveyed.

The molecule of camphoric acid contains two, and only two, asymmetric carbon atoms, that these carbon atoms are links in a closed carbon chain, and that each of them has a carboxyl group attached to it. It is further known that the asymmetric carbon atoms are not similar to each other, so that there can be no optical inactivity by internal compensation. To distinguish between these two asymmetric atoms, the prefixes ortho- and allo-, which are commonly used in application to the two carboxyl groups are employed. A discussion on the asymmetric carbon atom to which the ortho-carboxyl group is attached as the ortho-carbon atom, and of that to which the allo-carboxyl group is united as the allo-carbon atom, is presented.
