Novel heterocyclic aromatic compounds are provided that are useful in stimulating endogenous production or release of growth hormone, said compounds having the general structure of formula I wherein R 1 , R 1 ', R 2 , R 3 , R 4 , Xa, Y, Z and n are as described herein. The ...
Aromatic compounds, though having double bonds, are extremely stable and do not readily undergo the addition reactions characteristic of other unsaturated compounds. The stability and unreactivity of, for instance, a six-membered aromatic ring are associated with the presence of three pairs of ...
Heterocyclic compounds, or heterocycles, are cyclic compounds that have atoms of at least two different elements as members of the ring structure. Organic heterocycles contain one or more carbon atoms and, based on their electronic structure, are classified as saturated, unsaturated, and aromatic. Wh...

Heterocyclic aromatic compounds contain in their molecules at least one heteroatom and one carbon (see Chapter 16). Hydrogen connected to carbon atoms is frequently part of the heterocyclic molecules. Substitution of these hydrogen atoms with halogens leads to halogenated aromatic heterocyclic compounds....

Aromatic compounds, though having double bonds, are extremely stable and do not readily undergo the addition reactions characteristic of other unsaturated compounds. The stability and unreactivity of, for instance, a six-membered aromatic ring are associated with th...
1) aromatic heterocyclic compound 芳杂环化合物1. The surface-enhanced Raman scattering spectroscopy(SERS) analysis verifies that two nitrogen-containing or sulphur-containing aromatic heterocyclic compounds were chemisorbed onto the Ag-plated carbon fibers and formed a lie-down phase. 表面增强拉曼散射...
