The invention provides a small molecular compound of a NO donor. The small molecular compound is characterized in that the small molecular compound is a compound shown represented by structural formula I shown in the description, or a stereoisomer, a geometrical isomer, a tautomer, a racemate, a deuterated isotope derivative, a hydrate, a solvate, a metabolite, a pharmaceutically acceptable salt or a prodrug thereof; and in the formula I, ring A is a substituted or unsubstituted heteroaromatic ring, X is selected from (CH2)n, n is selected from 0, 1, 2 and 3, R is a substituent group of terminal -O-NO2, R is selected from hydrogen, a hydroxyl group, halogen, an amino group, a cyano group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group and a substituted or unsubstituted heteroalkyl group, and R and R are respectively and independently selected from hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted naphthenic base or an amino protecting group, or R and R are connected to form a substituted or unsubstituted cyclic heteroalkyl group. The compound has a high-activity inhibition effect on ROCK kinase.

A series of first generation dendritic guests from pentaerythritol derivatives have been designed and synthesized. Investigation of the complex structures of cucurbit[8]uril (Q[8]) and the guests based on the 1H NMR technique have revealed that the host Q[8] selectively included different branch(es) of the first generation dendritic guests and formed inclusion complexes with different structural conformations. The experimental results obtained from electronic absorption spectroscopy showed that the 1:1 ratio of Q[8]-based host-guest inclusion complexes have moderate stability with an average formation constants of 104 L mol-1. The single crystal structures of some of the guests (g5 and g6) and Q[8]-guest complexes (Q[8]-g4 and Q[8]-g6) further confirm but in some cases contradict the research results of the 1H NMR technique and electronic absorption spectroscopy in aqueous solution.

Cyclobutane diamines (i.e., cis- and trans-1,3-diaminocyclobutane, 6-amino-3-azaspiro[3.3]heptane, and 3,6-diaminospiro[3.3]heptane) are considered as promising sterically constrained diamine building blocks for drug discovery. An approach to the syntheses of their Boc-monoprotected derivatives has been developed aimed at the preparation of multigram amounts of the compounds. These novel synthetic schemes exploit classical malonate alkylation chemistry for the construction of cyclobutane rings. The conformational preferences of the cyclobutane diamine derivatives have been evaluated by X-ray diffraction and compared with the literature data on sterically constrained diamines, which are among the constituents of commercially available drugs.
