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.

Herein we describe the preparation and structure-activity relationship studies on range of stilbene based compounds and their antibacterial activity. Two related compounds, each bearing carboxylic acid moieties, exhibit good activity against several bacterial strains, including methicillin-resistant Staphylococcus aureus MRSA (ATCC 33592 and NCTC 10442). Compound 10 was most active against Moraxella catarrhalis with minimum inhibitory concentrations (MICs) of 0.12-0.25 μg mL-1 and against Staphylococcus spp. with MICs ranging from 2-4 μg mL-1. The derivative 17 showed increased activity with MICs of 0.06-0.25 μg mL-1 against M. catarrhalis and 0.12-1 against Staphylococcus spp. This level of activity is similar to that reported for S. aureus for antibiotics, such as vancomycin, with MICs of ≤2.0 μg mL-1 and clindamycin with MICs of ≤0.5 μg mL -1. As an indicator of toxicity, 17 was tested for its ability to lyse sheep erythrocytes, and showed low haemolytic activity. Such results highlight the value of tris(stilbene) compounds as antibacterial agents providing suitable properties for further development. Routes to new antibiotics: The preparation of and structure-activity relationship studies on a range of stilbene based compounds revealed two related compounds, each bearing carboxylic acid moieties, exhibiting pronounced activity against several bacterial strains including methicillin-resistant Staphylococcus aureus, MRSA (see scheme, dba = dibenzylidene acetone).
