実施例26 本発明化合物の細胞性免疫賦活活性の測定
本発明化合物の細胞性免疫賦活活性をマクロファージ(Mφ)に対するTNFα産生誘導活性を測定することにより調べた。
種々の菌体やその成分を投与した動物に、LPS(Lipopolysaccharide)を再投与するとその血清中に腫瘍の出血性壊死を主体とした、抗腫瘍作用を示すTNFαが産生される。本発明化合物にこの作用があるか否かを、一次刺激(priming:化合物添加)後、二次刺激(eliciting:LPS添加)を行い、培養上清中に産生されたTNFαの量をELISA法で測定することにより確認した。
具体的には、マウスの単球由来のマクロファージ様細胞(J774A.1株、1×105cell/100μl/well、10%−FCS加RPMI1640培地)に本発明化合物1を添加(10μg/ml)し、一次刺激処理(37℃、24時間)を行った(化合物添加群)後、培地を交換した。この際、対照として化合物1の代わりにLPSを添加し(LPS添加群)、同様に培地を交換した。その後、化合物添加群およびLPS添加群両者にLPS(1μg/ml)で二次刺激処理(37℃、48時間)を行い、培養液中に産生、放出されたTNFα濃度をELISA法で測定した。
結果を図1に示す。図1から、一次刺激処理のみでは、本発明化合物にTNFαの産生作用は見られないが、その後の二次刺激処理により、LPS添加群と比較してTNFαの産生が顕著に誘導されることが示された。
この結果から、本発明化合物は、単独ではMφ様細胞よりTNFαを産生させる作用は見られないが、産生を誘導させる一次刺激作用(約6倍の産生増強)が強く、免疫賦活剤として有用であることが示された。

Example 26 Measurement of cellular immunostimulatory activity of the compound of the present invention
The cellular immunostimulatory activity of the compound of the present invention was examined by measuring the TNFα production-inducing activity against macrophages (Mφ).
When LPS (Lipopolysaccharide) is re-administered to an animal that has been administered various fungal bodies and its components, TNFα that exhibits antitumor activity, mainly consisting of hemorrhagic necrosis of the tumor, is produced in the serum. Whether the compound of the present invention has this effect or not is determined by performing primary stimulation (priming: addition of compound) and then secondary stimulation (elimination: addition of LPS), and the amount of TNFα produced in the culture supernatant is determined by ELISA. This was confirmed by measuring.
Specifically, the compound 1 of the present invention was added to a monocyte-derived macrophage-like cell (J774A.1 strain, 1 × 10 5 cell / 100 μl / well, 10% -FCS-added RPMI 1640 medium) (10 μg / ml), After the primary stimulation treatment (37 ° C., 24 hours) (compound addition group), the medium was changed. At this time, LPS was added instead of Compound 1 as a control (LPS addition group), and the medium was changed in the same manner. Thereafter, both the compound addition group and the LPS addition group were subjected to secondary stimulation treatment (37 ° C., 48 hours) with LPS (1 μg / ml), and the concentration of TNFα produced and released in the culture medium was measured by ELISA.
The results are shown in FIG. From FIG. 1, it can be seen that the TNFα production action of the compound of the present invention is not observed only by the primary stimulation treatment, but the production of TNFα is significantly induced by the subsequent secondary stimulation treatment as compared with the LPS addition group. Indicated.
From this result, although the compound of the present invention alone does not produce an effect of producing TNFα from Mφ-like cells, it has a strong primary stimulating action (about 6 times production enhancement) to induce production and is useful as an immunostimulator. It was shown that there is.
Example 27 Herbicidal effect of the compound of the present invention
A test compound (compounds 1 to 7) was dissolved in a small amount of dimethyl sulfoxide and diluted to a predetermined concentration with a 1/2 Hutner culture solution to prepare a test solution. A certain amount was dispensed into wells (holes) in the titration plate, the test plants were placed on the floor, and the growth status was observed to determine the herbicidal effect of the test compound. The judgment was made according to the following criteria.
Judgment and evaluation criteria:
0: Growth is similar to untreated individuals.
1; Growth is slightly suppressed.
2; Growth is clearly suppressed.
3; Growth is dead or completely suppressed.
The composition of Hutner culture solution used in this example is shown in Table 2 below.

Test Example 1 (Duckweed; Lemna paucicostata Hegelm)
Fronds (one leaf) were isolated from a duckweed colony subcultured in a 1/2 Hutner culture at 25 ° C. under 5000 lux continuous illumination and placed in a test solution. It was kept in an incubator under 25 ° C. and 1000 lux continuous illumination for 5 days, and the number of growth fronts was examined.

(1) Preparation of test nematode (Caenorhabditis elegans N2)
Stage III larvae were selected from the population in sterile subculture (Sayer et., Al, 1963) and used for the test.
(2) Preparation of test solution
A test compound (compound 8) and methyl isothiocyanate (MITC) as a control agent were weighed to prepare a 1% solution of DMSO. M-9 buffer solution (Brenner, 1974) containing 100 ppm of Tween 20 was added thereto to make a 500 ppm test solution.
(3) Test method
40 μl of M-9 buffer solution was put into one hole of a three-hole slide glass (hole diameter: 15 mm, depth: 1 mm), and 10 nematodes were transferred with a transplantation needle, and then 40 μl of 500 ppm test solution was added. In addition, the mixture was lightly stirred to a final concentration of 250 ppm. The slide glass was placed in a moist chamber, kept at about 22 ° C., and the number of live insects was examined after 24 and 48 hours. In addition, the repetition was set to 3 with respect to 1 process, and the final density | concentration of the control agent was 200 ppm.
