Eight new diarylheptanoids, a 1.2:1 mixture of (3S)- and (3 R)-1-(4-hydroxyphenyl)-7-phenyl-(4 E,6 E)-4,6-heptadien-3-ol (1a and 1b), a racemic mixture of (3S)- and (3 R)-1-(4-hydroxyphenyl)-3-methoxy-7-phenyl-(4 E,6 E)-4,6-heptadiene (2a and 2b), a ca. 1:1 mixture of (3S)- and (3 R)-1-(4-hydroxy-3-methoxyphenyl)-3-methoxy-7-phenyl)-(4 E,6 E)-4,6-heptadiene (3a and 3b), 3-acetoxy-1-(3,4-dihydroxyphenyl)-7-phenylheptan-5-ol (4), (3 R)-1-(4,5-dihydroxyphenyl)-7-phenyl-(6 E)-6-hepten-3,2′-epoxide (5), and thirteen known diarylheptanoids, 6-12, a 3:1 mixture of 13a and 13b, and 14-17, were isolated from the rhizomes of Curcuma comosa from Sakon Nakhon, northeastern part of Thailand. The isolated compounds were evaluated for their antiinflammatory activities on the inhibition of lipopolysaccharide-induced nitric oxide production in macrophage RAW 264.7 cells and the diarylheptanoids 1a and 1b mixture and 14 exhibited potent inhibitory activity.

The 6-Mercaptopurine (6-MP) is a purine sulphur derivative used in the treatment of children with leukaemia as an antitumor medication. Nonetheless, the anti-proliferation and anti-rheumatoid arthritic activities of the drug have not been previously described. Therefore, the current study objective was to determine the cytotoxicity effects of 6-MP, 6-mercaptopurine riboside (6-MPR), 6-thioguanine (6-TG) and 6-thioxanthine (6-TX) on murine macrophages (RAW 264.7) and rabbit synoviocytes (HIG-82) cell lines. An inflammatory stage of RAW 264.7 and HIG-82 cell lines stimulated with Escherichia coli lipopolysaccharide (LPS) and phorbol-12-myristate acetate (PMA), respectively were treated with the drugs at a serials concentration 3.125 – 100 µM. Subsequently, the MTT assay was used to determine the viability of cells. The inhibitory effects were measured based on nitric accumulation in the conditioned media. The results showed that all drugs tested did not show any cytotoxic effect on both cell lines at low and medium concentrations, which the HIG-82 cell viability was more than 80%. However, the drugs display anti-proliferation property on RAW 264.7 cells compared to control. Reduction on cell proliferation was found on all tested drugs. Among its, the diclofenac significantly reduced the proliferation on HIG-82 cell compared to other drug compounds. Inhibitory effects of compound on nitric oxide production PMA-stimulated HIG-82 had only a small inductive effect, but excellent inhibition was observed on RAW 264.7 cell. Meanwhile, 100 μM 6-thioguanine and diclofenac had cytotoxic effect to RAW 264.7 and HIG-82 cell respectively. All thiopurines enhanced the proliferation of HIG-82 and RAW 264.7 cells with no cytotoxic effects. This finding opens new avenues for treating RA and the anti-rheumatic activities during synovial inflammation stage of RA. The inhibitory effects of 6-MP and 6-MPR to inflammatory cells marker such as synovial fibroblast and macrophages by proliferating healthy synoviocytes more potenly than 6-TG and 6-TX. The current study has demonstrated the potential use of 6-MP and its associated thio compounds in the in-vitro approach of HIG-82 cell culture in curing rheumatoid arthritis disease.
