Definitions
- the present invention relates to a rotaxane compound that can be used as an anticancer agent and an anticancer agent containing this as an active ingredient.
- anticancer agents exert their anticancer action only after being absorbed inside cancer cells. For this reason, it has been considered that a drug having a low molecular weight and a stable structure is effective as an anticancer agent in order to facilitate the uptake of cancer cells via a receptor.
- anticancer drugs that can be easily absorbed into cancer cells via receptors are therefore easily excreted from the cells, and therefore cannot remain in the cancer cells for a sufficient time to exert anticancer effects. There was a problem that there was.
- anticancer agents that are easily absorbed through receptors are easily taken up not only by cancer cells but also by normal cells, so that local treatment is difficult and side effects caused by damaging normal cells The problem was also to occur.
- the rotaxane compound disclosed in Patent Document 2 had a structure as shown in Chemical Formula 2 below.
- the compound represented by the chemical formula 2 has been shown to have an inhibitory effect on the growth of cancer cells as described in the patent document.
- the present invention has a molecular weight larger than that of the above compound, and is equivalent to or higher than that of the compound.
- the object is to provide a rotaxane compound having a cancer drug effect.
- the rotaxane compound according to the present invention includes a compound represented by the following chemical formula 3 as a basic skeleton (where m ⁇ 3 and n ⁇ 2, X is an anionic molecule or anion Ion atoms).
- the compound including the above-mentioned compound as a basic skeleton means not only the above-mentioned compound itself but also one obtained by adding an appropriate substituent to the above-mentioned compound. That is, in the present invention, a functional group may be included in the cyclic portion as long as each compound has the basic skeleton. Specific functional groups are not particularly limited as long as they can be introduced structurally. For example, mercaptomethyl group, mercapto group, aminomethyl group, amino group, hydroxyl group, hydroxymethyl group, carboxyl group, carboxymethyl, for example.
- anion molecule or anion atom represented as “X” is not particularly limited, and specific examples thereof include perchlorate ion, trifluoromethanesulfonate ion, hexafluorophosphate ion, trifluoroacetic acid. Ions, tetrafluoroborate ions and the like.
- the rotaxane compound represented by this chemical formula 5 is formally [2] [bis (3,5-dimethylphenylcarboxypentyl) ammonium-rotaxa- [2,5,8,11,13,16,19,22-octaoxa-1,12 It is a compound called (1,2) -dibenzenacyclodocosaphane]] trifluoromethanesulfonate and has a molecular weight of 1052.
- Each of these rotaxane compounds is composed of two parts: a rod-like part having relatively large molecules bonded to both ends, and a cyclic part (crown ether) into which the rod-like part is inserted.
- the annular portion Since the annular portion is in a state where the rod-like portion is inserted, the annular portion can be moved with the rod-like portion as an axis. However, since a relatively large molecule is bonded to both ends of the rod-shaped portion, the annular portion cannot be detached from the rod-shaped portion as a stopper.
- the rod-like portion and the annular portion have a connected structure, the rod-like portion and the annular portion are not bonded by a covalent bond. For this reason, the shape of the molecule is easily changed, and uptake through a receptor becomes relatively difficult. However, when this is introduced into a cancer cell, proliferation of the cancer cell is suppressed. That is, the rotaxane compound according to the present invention acts as an active ingredient of an anticancer agent.
- an anticancer agent that is difficult to be excreted from cancer cells and is suitable for local treatment.
- the target product was a white foamy solid, yield 157 mg, yield 10%.
- the 1 H NMR spectrum (400 MHz, CDCl 3 , 298 K) of the obtained target product was as follows and was confirmed to be the compound shown on the right side of the above chemical formula 6.
- the target product was a white foamy solid, yield 142 mg, yield 9%.
- the target product was a white foamy solid with a yield of 388 mg and a yield of 57%.
- the 1 H NMR spectrum (400 MHz, CDCl 3 , 298 K) of the obtained target product was as follows and was confirmed to be the compound shown on the right side of the above chemical formula 8.
- This TRO-A0001 is a compound described in Patent Document 1 and is represented by the structural formula of the following chemical formula 9.
- the total volume was 1000 ⁇ L. 100 ⁇ L of this was dispensed into each well of a 96-well microplate and cultured in a CO 2 incubator for 24 hours. Thereafter, 10 ⁇ L of a reagent for measuring living cells (Tetra Color ONE, Seikagaku Corporation) was added to each well of a 96-well microplate, and reacted for 2 hours in a CO 2 incubator. After the reaction, ultraviolet absorbance at 450 nm (control wavelength: 620 nm) was measured after 72 hours using a microplate reader. Note that the greater the absorbance, the greater the number of living cells.
- the present invention can be used as an anticancer agent.

Abstract
Description
しかし、受容体を介してガン細胞内に容易に吸収され得る抗ガン剤はそれゆえに逆に細胞から排出されやすいため、抗ガン作用を発揮するに十分な時間、ガン細胞内に留まっていられないことがあるという問題点があった。また、このような、受容体を介して吸収されやすい抗ガン剤はガン細胞のみならず正常細胞にも取り込まれやすいため、局所的な治療が困難であるとともに、正常細胞を傷害することによる副作用の問題も生じることとなっていた。
本発明に係るロタキサン化合物のうち、最も低分子のものは下記化学式4に示すような、m=2かつn=3の場合である。
また、本発明に係るロタキサン化合物については、m,n≦5であることが望ましい。この場合、mとnの可能な組み合わせは上記化学式4の(2,3)の場合の他、(2,4)、(2,5)、(3,3)、(3,4)、(3,5)、(4,4)、(4,5)及び(5,5)の9通りあり、このようなロタキサン化合物のうち、最も高分子のものは下記化学式5に示すような、m=n=5の場合である。
これらのロタキサン化合物はいずれも、両端に比較的大きな分子が結合した棒状部分と、この棒状部分が挿入された環状部分(クラウンエーテル)の2つの部分からなる。環状部分は、棒状部分が挿入された状態であるため、棒状部分を軸として移動することができる。しかしながら、棒状部分の両端には比較的大きな分子が結合しているため、これがストッパーとなって環状部分が棒状部分から離脱することはできない。
本発明に係るロタキサン化合物のうち、m=2、n=3のものを「TRO-A0014」とする。このTRO-A0014は、下記化学式6に示すような反応式にて合成された。

(2)TRO-A0015
本発明に係るロタキサン化合物のうち、m=n=3のものを「TRO-A0015」とする。このTRO-A0015は、下記化学式7に示すような反応式にて合成された。
δ 7.54(s, 4H), 7.17(s, 2H), 6.86(brd, 8H), 4.18-4.17(m, 8H),4.12(t,J=6.4Hz,4H),3.88-3.87(m,8H),3.73(brd,8H),3.56-3.47(m,4H),2.30(s,12H),2.04-1.94(m,4H)(単位:ppm)。
(3)TRO-A0010
本発明に係るロタキサン化合物のうち、m=n=5のものを「TRO-A0010」とする。下記化学式8に示すこのTRO-A0010は、下記方法にて合成された。
δ 7.59(s,ArH,4H),7.18(s,ArH,2H),6.89-6.83(m,ArH,8H),4.14(m,CH2,8H),4.08(t,J=6.4Hz,CH2,4H),3.86(m,CH2,8H),3.70(m,CH2,8H),3.25(m,CH2,4H),2.34(s,dimethyl of end cap,CH3,12H),1.54-1.44(m,CH2,8H),1.26-1.17(m,CH2,4H)(単位:ppm)。
(4)TRO-A0001
なお、上記各ロタキサン化合物の比較対照として、m=n=2であるロタキサン化合物「TRO-A0001」も用いた。なお、このTRO-A0001は前記特許文献1記載の化合物であり、下記化学式9の構造式で表されるものである。
(5-1)実験条件
ガン細胞として、マウス結腸ガン細胞由来株のColon-26、ヒト膠芽ガン細胞由来株のT98G及びヒト皮膚悪性黒色腫細胞由来株のG361を使用した。各ガン細胞はRPMI1640に10%FBSや0.5%Penicillin-streptomycinを加えたものを基本培地とし、5%CO2存在下、37℃、加湿条件で培養を行った。十分コンフルエントな状態に培養した各ガン細胞5.0×104個を1.5mLチューブに培地とともに播種し、vehicle(溶媒)としてのDMSOに各ロタキサン化合物を溶解したものを、所定濃度となるように加えて全量を1000μLとした。これを96ウェルマイクロプレートの各ウェルに100μLずつ分注し、CO2インキュベーターで24hr培養した。その後、生細胞測定用試薬(Tetra Color ONE、生化学工業)を96ウェルマイクロプレートの各ウェルに10μL加え、CO2インキュベーターで2hr反応させた。反応後、マイクロプレートリーダーを使用して450nm(対照波長:620nm)の紫外吸光度を72hr後に測定した。なお、その吸光度が大きいほど生細胞数が多いことになる。
ガン細胞としてColon-26を用い、TRO-A0014及びTRO-A0015の抗ガン作用を上記(5-1)の通り検証した。その結果を図1に示す。なお、図中の「Vehicle」とはロタキサン化合物を加えず溶媒としてのDMSOのみを加えた場合を意味し、「Control」とはロタキサン化合物もDMSOも加えず細胞のみで培養した場合を意味する。
その結果、比較対照としてのTRO-A0001(m=n=2)では濃度2.5μM以上で細胞に対する障害効果が現れているのものの、1.25μMでは「Control」とほとんど差はなく効果は見られなかった。それに対し、TRO-A0014(m=2,n=3)及びTRO-A0015(m=n=3)では1.25μMで既に細胞障害効果が明らかに認められた。
(5-3)TRO-A0010の抗ガン作用
ガン細胞としてT98G及びG361を用い、TRO-A0010の抗ガン作用を上記(5-1)の通り検証した。その結果を図2に示す。
その結果、T98GではTRO-A0010の抗ガン作用はTRO-A0001とほぼ同等であった。また、G361ではいずれのロタキサン濃度においてもTRO-A0010の細胞障害効果はTRO-A0001より高いことが分かった。よって、TRO-A0010(m=n=5)の抗ガン作用はTRO-A0001(m=n=2)とほぼ同等か、細胞株によってはより強いことが明らかとなった。
