- Anticancer and anti-inflammatory activities of 1,8-naphthyridine-3-carboxamide derivatives
-
Several 1,8-naphthyridine-3-carboxamide derivatives (8-23) were synthesized and tested for in vitro cytotoxicity against eight cancer cell lines and a normal cell line. Compound 12 exhibited high cytotoxicity (IC50 = 1.37 μM) in HBL-100 (breast) cell line while compounds 17 (IC50 = 3.7 μM) and 22 (IC50 = 3.0 μM) have shown high cytotoxicity in KB (oral) and SW-620 (colon) cell lines, respectively. The synthesized 1,8-naphthyridine-3-carboxamides were also evaluated for anti-inflammatory and myeloprotective activities, indicated by modulation in cytokine and chemokine levels secreted by dendritic cells.

- Synthesis and in vitro antitumor activity of novel naphthyridinone derivatives
-
A series of naphthyridinone derivatives based on 1a (a precursor of Voreloxin) were designed and synthesized. Seven compounds having >70% inhibition against HL60 at 30 μmol/L were further evaluated for their in vitro antitumor activity by SRB assay. Results reveal that thiazol-2-yl and 3-aminomethyl-4-benzyloxyimino-3-methylpyrrolidin-1-yl groups are optimal at the N-1 and C-7 positions of naphthyridinone core, respectively. 10j exhibits broad-spectrum activity (IC50: 100-fold more potent than the two references against eight of these cell lines.

- Synthesis and Structure-Activity Relationships of Novel 7-Substituted 1,4-Dihydro-4-oxo-1-(2-thiazolyl)-1,8-naphthyridine-3-carboxylic Acids as Antitumor Agents. Part 2
-
We have previously reported that a series of 7-substituted 6-fluoro-1,4-dihydro-4-oxo-1-(2-thiazolyl)-1,8-naphthyridine-3-carboxylic acids possess moderate cytotoxic activity. In a further attempt to find clinically useful antitumor agents, we investigated the structure-activity relationships (SARs) of a new series of compounds obtained by changing the C-6 position of the fluorine atom in addition to the C-5 and C-7 positions and evaluating their cytotoxic activity against several murine and human tumor cell lines. Our results showed that the 6-unsubstituted 1,8-naphthyridine structure had the most potent cytotoxic activity against murine P388 leukemia twice that of the 6-fluoro analogue. In addition, introduction of an amino group at the C-5 position did not have any substantial effect on the cytotoxic activity, while both the 5-chloro and 5-trifluoromethyl groups decreased the cytotoxic activity by 5- to 10-fold. Moreover, aminopyrrolidine derivatives at the C-7 position showed more potent cytotoxic activity than other amines or carbon derivatives. Among the 7-(3-aminopyrrolidinyl) derivatives, the trans-3-methoxy-4-methylaminopyrrolidinyl derivative (271) was determined to have potent cytotoxic activity in both in vitro and in vivo assays and high water solubility. Finally, the (S,S)-isomer (AG-7352, 3) of 271, with a cytotoxic activity against human tumor cell lines more potent than that of etoposide, was selected for further development.
