Phloroglucinol compounds isolated from Dryopteris fragrans (L.) Schott showed a variety of biological activities, such as anticancer and anti-inflammatory. In this study, we have made a number of modifications around the scaffold of phloroglucinol and synthesized phloroglucinol derivatives A1–A9, B1–B9, and C1–C3. We synthesized these compounds and investigated their effect on four human cancer cell lines (A-549, MCF-7, Hela, HepG2 cell lines) via MTT assay in vitro. The results revealed that all compounds exhibited certain antiproliferative activities on cancer cell lines and excellent inhibitory effects on MCF-7, in which compound C2 was the best with the IC50 value of 18.49 μM, exceeding that of 5-fluorouracil. Moreover, the cell apoptosis test showed that compound C2 induced apoptosis in a concentration-dependent manner. Furthermore, the results of molecular docking analysis explained the probable interaction between the active compounds and active sites of target protein 4I22 and 1OG5.

Paragraph 0068-0073, (2021/05/12)
The invention provides a dihydropyrazole MurA enzyme inhibitor molecule as well as a preparation method and application thereof. The structural formula is shown in the specification, R is a direct-connected alkyl group with the chemical formula of CnH2n+1, and n is equal to 1-7. The preparation method comprises the following steps of by taking acetophenone substances with different substituent groups and 4-(4-methyl piperazinyl) benzaldehyde as raw materials, carrying out aldol condensation reaction under an alkaline condition to obtain an intermediate, and synthesizing a target compound with a structural formula by using the intermediate, hydrazine hydrate and an organic acid with an R-COOH structure. The dihydropyrazole MurA enzyme inhibitor molecule provided by the invention has a bacterial inhibition effect, has an MurA enzyme inhibition effect, and also has an effect of interfering synthesis of bacterial cell walls.

Paragraph 0088; 0094; 0095, (2019/09/05)
The present inventors synthesized described portulacanone derivatives (compound 1: R^1, R^2 = H; and compound 2: R^1, R^2 = H), natural homoisoflavonoids (andplusmn;)-portulacanone A-C (compound 4: R^1 = OMe, R^2 = H; compound 8: R^1, R^2 = OMe; and compound 9: R^1 = OH, R^2 = OMe), and derivatives thereof (compound 3: R^1 = OMe, R^2 = H; compound 5: R^1 = OH, R^2 = H, and compound 7: R^1, R^2 = OMe), and thus evaluated ability to inhibit NO production in LPS-induced RAW 264.7 macrophages as an indicator of anti-inflammatory activity. All tested compounds showed no clear cytotoxicity and inhibited NO production in a concentration dependent manner in RAW 264.7 macrophages. A compound 3 (97.2% inhibition at 10 andmu;M; IC50 = 1.26 andmu;M) shows a significant inhibition effect compared to a compound 1 (91.4% inhibition at 10 andmu;M; IC50 = 1.75 andmu;M) and a compound 7 (83.0% inhibition at 10 andmu;M; IC50 = 2.91 andmu;M). Compounds of the present invention are useful for developing NO producing targeted anti-inflammatory drugs.COPYRIGHT KIPO 2019
