 以上のとおり各種理化学的性状が得られたナナオマイシンHに一致する化合物はこれまで報告されていないことから、ナナオマイシンHは新規物質であると考えられる。 As described above, since no compound corresponding to nanaomycin H that has obtained various physicochemical properties has been reported so far, nanaomycin H is considered to be a novel substance.
(実施例3)TGF-βにより上皮間葉転換誘導されたMDCK(イヌ上皮細胞株)に対する影響
 細胞培養用ディッシュにイヌ腎臓尿細管上皮由来細胞株MDCK(以下、「MDCK細胞」という。)を、イーグル最少必須培地(以下、「MEM培地」という。)(10%ウシ胎児血清アルブミン、1%MEM非必須アミノ酸溶液、1%ピルビン酸ナトリウム,1%ペニシリン-ストレプトマイシン溶液、1%グルタミン)中、37℃、5%COインキュベーターでセミコンフルエントに維持されるように継代培養を行った。この細胞をトリプシン-EDTA溶液で処理し、終濃度10ng/mLのTGF-βと0.001%のBSAを含む前記培地に細胞を播種し、3日間培養した。ブランクとしてTGF-βを加えず、BSAのみを添加した培地中で同様に3日間培養した細胞を用意した。これらの細胞を96ウェルにMDCK細胞を20,000細胞/ウェル(コンフルエント状態)および2,000細胞/ウェル(薄まき状態)で調整した。
Example 3 Effect on MDCK (Canine Epithelial Cell Line) Induced to Epithelial-mesenchymal Transition by TGF-β A canine kidney tubular epithelium-derived cell line MDCK (hereinafter referred to as “MDCK cell”) is used as a dish for cell culture. Eagle's minimum essential medium (hereinafter referred to as “MEM medium”) (10% fetal bovine serum albumin, 1% MEM non-essential amino acid solution, 1% sodium pyruvate, 1% penicillin-streptomycin solution, 1% glutamine) Subculture was carried out so as to be maintained semi-confluent in a 37 ° C., 5% CO 2 incubator. The cells were treated with a trypsin-EDTA solution, the cells were seeded in the medium containing TGF-β having a final concentration of 10 ng / mL and 0.001% BSA, and cultured for 3 days. As a blank, cells cultured in the same manner for 3 days in a medium supplemented with only BSA without adding TGF-β were prepared. These cells were adjusted to 96 wells and MDCK cells were adjusted to 20,000 cells / well (confluent state) and 2,000 cells / well (thinned state).
 それぞれのウェルに終濃度50μg/mlになるようにDMSOに溶解したナナオマイシンH(終濃度0.5%DMSO)あるいはナナオマイシンメチルエステル体(終濃度0.5%DMSO)を添加して、37℃、5%COインキュベーターで24時間培養し、形態観察および生細胞定量キット(MTSアッセイ)で毒性・増殖試験を行った。その結果を図1に示した。ナナオマイシンHはコンフルエント状態ではほとんど毒性を示さなかったが,薄まき状態になって40%程度の細胞毒性を示した(DMSO比)。一方でTGFβを処理してEMTを誘導した細胞群では,ほとんどの細胞が死滅した。 Nanaomycin H (final concentration 0.5% DMSO) or nanaomycin methyl ester (final concentration 0.5% DMSO) dissolved in DMSO to a final concentration of 50 μg / ml was added to each well. The cells were cultured for 24 hours in a 5% CO 2 incubator at 0 ° C., and the toxicity / proliferation test was performed using a morphology observation and live cell quantification kit (MTS assay). The results are shown in FIG. Nanaomycin H showed almost no toxicity in the confluent state, but showed a cytotoxicity of about 40% in the thinned state (DMSO ratio). On the other hand, most cells died in the cell group in which EMT was induced by treating TGFβ.
(実施例4)移動細胞に対する毒性
 光照射に応じて細胞パターニングが可能な機能性基板(Biomaterials, 2012, Voi. 33, pp. 2409-2428;Shimizu et al. Analytical Sciences,印刷中)を利用して,幾何学的に規定された円形領域(φ=150μm)にMDCK細胞のコロニーを形成した後,その後に2次照射によって細胞移動を誘導した。この際に,終濃度50μg/mlのナナオマイシンHおよび0.5%DMSO,50μg/mlのナナオマイシンHメチルエステル体および0.5%DMSO,もしくはDMSOのみを添加した培地を用意し,これらの培地中での細胞の移動挙動を,培養装置を装着した位相差顕微鏡下で観察した。
(Example 4) Toxicity to mobile cells Using a functional substrate (Biomaterials, 2012, Voi. 33, pp. 2409-2428; Shimizu et al. Analytical Sciences, in print) capable of cell patterning in response to light irradiation. Then, after colonies of MDCK cells were formed in a geometrically defined circular region (φ = 150 μm), cell migration was then induced by secondary irradiation. At this time, a medium containing a final concentration of 50 μg / ml nanaomycin H and 0.5% DMSO, 50 μg / ml nanaomycin H methyl ester and 0.5% DMSO, or DMSO alone was prepared. The cell migration behavior in the culture medium was observed under a phase contrast microscope equipped with a culture device.
 DMSOのみを含む培地では,コロニーが拡大していく様子が観察されるが,ナナオマイシンHやナナオマイシンHメチルエステル体を添加したほうではコロニー周りの細胞が選択的に死んでいく様子が観察された。MDCK細胞は先導端に上皮間葉転換した細胞を出現させて集団で移動するため,この結果から上皮間葉転換した細胞に特異的に効果をしていることがわかった(図2)。 In the medium containing only DMSO, the colony is observed to expand, but the cells around the colony are selectively killed when nanomycin H or nanomycin H methyl ester is added. It was. Since MDCK cells appeared in the epithelial-mesenchymal transition cells at the leading end and migrated in the population, it was found that this result has a specific effect on epithelial-mesenchymal transition cells (FIG. 2).
 以上の結果から、ナナオマイシンHおよびナナオマイシンHメチルエステル体は上皮間葉転換が誘導された細胞の増殖抑制効果があることが示された。 From the above results, it was shown that nanaomycin H and nanaomycin H methyl ester have an effect of suppressing the proliferation of cells in which epithelial-mesenchymal transition was induced.

 それぞれのウェルに終濃度100μg/mlおよび5μg/mlになるようにDMSOに溶解したナナオマイシンH(終濃度0.5%DMSO)あるいは終濃度50μg/mlおよび5μg/mlになるようにDMSOに溶解したナナオマイシンI、JおよびK(終濃度0.5%DMSO)を添加して、37℃、5%COインキュベーターで24時間培養し、形態観察および生細胞定量キット(MTSアッセイ)で毒性・増殖試験を行った。その結果を図3に示した。ナナオマイシンHは6,000細胞/ウェルで調整した試験では100μg/mlおよび5μg/mlにTGF-βにより上皮間葉転換誘導した細胞に対しより高い殺活性を示した。同様に、ナナオマイシンI、JおよびKもナナオマイシンHと同様な効果が認められた。 Nanaomycin H (final concentration 0.5% DMSO) dissolved in DMSO to a final concentration of 100 μg / ml and 5 μg / ml in each well or dissolved in DMSO to a final concentration of 50 μg / ml and 5 μg / ml , And cultivated in a 37 ° C, 5% CO 2 incubator for 24 hours, followed by morphological observation and live cell quantification kit (MTS assay). A proliferation test was performed. The results are shown in FIG. Nanaomycin H showed higher killing activity against cells induced to undergo epithelial-mesenchymal transition by TGF-β at 100 μg / ml and 5 μg / ml in studies adjusted at 6,000 cells / well. Similarly, nanaomycin I, J, and K showed the same effect as nanaomycin H.
