Paragraph 0475-0481, (2020/06/17)
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 novel ferrocene-pyrazole derivatives containing nitric oxide donors as COX-2 inhibitors for cancer therapy were designed, synthesized and biologically evaluated. Among them, compound 7l displayed the most potent inhibitory against COX-2 (IC50 = 0.82 μM) and antiproliferative activities against Hela cells (IC50 = 0.34 μM) compared with Celecoxib (IC50 = 0.38 and 7.91 μM). The further mechanistic studies revealed that 7l could induce apoptosis of Hela cells by mitochondrial depolarization and the antiproliferative activities of 7l were positively correlated with the levels of intracellular NO release in Hela cells. Most notably, 7l could dramatically suppress tumor growth in Hela cells xenografted mouse model. In summary, compound 7l may be promising candidates for cancer therapy.

Paragraph 0244, (2013/07/05)
1,5-diaryl-2-alkylpyrrole-3-substituted nitro esters, of Formula (I) are provided. Such compounds are potent and selective COX-2 inhibitors which are able to release NO in concentrations that make it possible to counteract the side effects due to selective COX-2 inhibition, without giving rise to hypotensive effects. Formula (I) includes compounds wherein the groups R′ and R″ are: —H, —F, —Cl, —Br, —CH3, —CF3, —OCH3, —SCH3, R1 is methyl, ethyl, trifluoromethyl, hydroxymethyl, methoxymethyl and the substituent in position ?3 of the pyrrole ring is a chain, where the groups X, Y, Z, W and R2 are: X is a carbonyl or a group —(CHR3)—, Y is an oxygen atom or the group —NR3— and Z is a carbonyl or a group —(CHR3)—, or a [—CH(COOH)—] group, or a group —(NR3)—, W is an aliphatic chain substituted with one or two (—O—NO2) groups, R2 is: —H, —OH, —OCH3, or —NHR3. R3 is: —H, —CH3, —CH2CH3, [—CH2(CH3)2]. R′″ is methylsulphonyl or sulphonamido. Pharmaceutical formulations and methods of making an using such formulations are also provided.
