Description

一种阳离子脂质化合物、包含其的组合物及应用Cationic lipid compound, composition containing the same and application thereof 技术领域Technical Field

本发明涉及生物医药领域，具体的说，本发明涉及一种阳离子脂质化合物、包含其的组合物及应用。The present invention relates to the field of biomedicine, and in particular to a cationic lipid compound, a composition containing the same and applications thereof.

背景技术Background Art

核酸(nucleic acids，RNA)通过体内表达蛋白而具有巨大的潜力，根据蛋白功能的不同，展现出预防与治疗的效果，但裸露的RNA在体内循环时间短，被细胞内化效率低，且极易被肾脏清除或者被体内RNase降解，实际效果大打折扣。为了更好的将核酸递送到靶点用以提升其预防和治疗作用，阳离子脂质化合物与相关制剂是关键技术之一。Nucleic acids (RNA) have great potential by expressing proteins in the body. Depending on the function of the protein, they can show preventive and therapeutic effects. However, naked RNA has a short circulation time in the body, low efficiency of cell internalization, and is easily cleared by the kidneys or degraded by RNase in the body, which greatly reduces the actual effect. In order to better deliver nucleic acids to the target site to enhance its preventive and therapeutic effects, cationic lipid compounds and related preparations are one of the key technologies.

LNP(lipid nanoparticles)作为目前主流递送载体，其能够与mRNA结合提高mRNA的体内循坏时间，控制体内逃逸来提高其转染率，增加蛋白表达发挥作用。LNP一般由四种成分组成，包括：(1)阳离子脂质，提供电荷包载mRNA分子；(2)支撑磷脂，提供双分子层支撑，有助于内体逃逸；(3)胆固醇，增强LNP的稳定性，促进膜融合；(4)PEG脂质，减小LNP的粒径，提升体内循环时间。LNP (lipid nanoparticles) is currently the mainstream delivery carrier. It can bind to mRNA to increase the in vivo circulation time of mRNA, control its escape in the body to increase its transfection rate, and increase protein expression. LNP is generally composed of four components, including: (1) cationic lipids, which provide charge to encapsulate mRNA molecules; (2) supporting phospholipids, which provide bilayer support and help endosomal escape; (3) cholesterol, which enhances the stability of LNP and promotes membrane fusion; (4) PEG lipids, which reduce the particle size of LNP and increase the in vivo circulation time.

在体内，阳离子作为LNP关键的成分之一，能够对LNP制剂的无稳定性和作用效力产生巨大的影响，本发明提供一类新型高效、低毒的阳离子化合物。In vivo, cations, as one of the key components of LNP, can have a significant impact on the instability and efficacy of LNP preparations. The present invention provides a new class of highly effective, low-toxic cationic compounds.

实施例1Example 1

化合物1的合成路线如下：
The synthetic route of compound 1 is as follows:

步骤1：Step 1:

将化合物1-1(5.0g)溶于DCM(200ml)，室温搅拌，依次称取1-乙基-(3-二甲基氨基丙基)碳酰二亚胺盐酸盐(EDCI，12.3g)，4-二甲氨基吡啶(DMAP，262mg)，三乙胺(6.51g)和正癸醇(6.79g)分批加入反应体系，室温搅拌16h。取少量反应液稀释与1-1标样对照点板(PE/EA＝10/1，磷钼酸和溴甲酚绿)，观察到极性变小的新点。反应液加水淬灭，分液，有机相减压蒸发，加适量硅胶拌样、纯化(80g正相柱，PE/EA，0-0％5min，0-10％20min，10-10％10min，流速40ml/min)，点板监测，将纯产物部分馏分蒸发，得到无色油状液体化合物1-2(6.0g，54.5％收率)。Compound 1-1 (5.0 g) was dissolved in DCM (200 ml), stirred at room temperature, 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDCI, 12.3 g), 4-dimethylaminopyridine (DMAP, 262 mg), triethylamine (6.51 g) and n-decanol (6.79 g) were weighed in batches and added to the reaction system, and stirred at room temperature for 16 h. A small amount of the reaction solution was diluted with the 1-1 standard sample control plate (PE/EA=10/1, phosphomolybdic acid and bromocresol green), and new spots with reduced polarity were observed. The reaction solution was quenched with water, separated, and the organic phase was evaporated under reduced pressure. An appropriate amount of silica gel was added for sample mixing and purification (80 g normal phase column, PE/EA, 0-0% 5 min, 0-10% 20 min, 10-10% 10 min, flow rate 40 ml/min) was performed using a spot plate for monitoring. Part of the pure product fractions were evaporated to give a colorless oily liquid compound 1-2 (6.0 g, 54.5% yield).

步骤2：Step 2:

向化合物1-2(6.0g)的二氯甲烷溶液(50ml)溶液中加入三氟乙酸(15ml)。将混合物在室温下搅拌16小时。TLC显示化合物1-2完全消失，有一个极性变大的点生成。将反应液旋干，加入饱和碳酸氢钠水溶液(100ml)淬灭多余的三氟乙酸，乙酸乙酯(100ml×2)萃取，有机相经无水硫酸钠干燥，过滤，浓缩后，加适量硅胶和DCM拌样、纯化(80g正相柱，PE/EA，0-0％5min，0-50％20min，50-50％min，流速50ml/min)得到白色固体化合物1-3(4.5g，93％收率)。Trifluoroacetic acid (15 ml) was added to a solution of compound 1-2 (6.0 g) in dichloromethane (50 ml). The mixture was stirred at room temperature for 16 hours. TLC showed that compound 1-2 completely disappeared and a point with increased polarity was generated. The reaction solution was spin-dried, saturated sodium bicarbonate aqueous solution (100 ml) was added to quench the excess trifluoroacetic acid, and ethyl acetate (100 ml × 2) was used for extraction. The organic phase was dried over anhydrous sodium sulfate, filtered, concentrated, and added with appropriate amount of silica gel and DCM to mix the sample and purify (80 g normal phase column, PE/EA, 0-0% 5 min, 0-50% 20 min, 50-50% min, flow rate 50 ml/min) to obtain white solid compound 1-3 (4.5 g, 93% yield).

步骤3：Step 3:

将化合物1-3(300mg)溶于超干二氯甲烷(5ml)，在冰浴下搅拌，依次加入超干吡啶(115mg)和三光气(86mg)，冰浴下搅拌0.5h。取少量反应液与1-3标样对照点板(PE/EA＝1/1，磷钼酸)，观察到极性变小的新点。反应液减压蒸发，所得固体加超干二氯甲烷(5ml)溶解后，滴加入化合物1-(2-羟乙基)-4-甲基哌嗪(500mg)和吡啶(10mL)的混合溶液中，滴加完成后，反应液在70℃下搅拌三小时，溶液为橙黄色，TLC(DCM/MeOH/NH4OH＝10/1/0.1,磷钼酸)显示，在吡啶下方有一个新点生成，加适量硅胶和二氯甲烷拌样、纯化(10g正相柱，DCM:DCM/MeOH/NH4OH，0-0％5min，0-70％20min，70-70％10min，流速20ml/min)得到淡黄色油状液体化合物1(200mg，47％收率)。化合物1的氢谱图见图1。Compound 1-3 (300 mg) was dissolved in ultra-dry dichloromethane (5 ml), stirred in an ice bath, ultra-dry pyridine (115 mg) and triphosgene (86 mg) were added in sequence, and stirred in an ice bath for 0.5 h. A small amount of the reaction solution was taken and spot-plated with the 1-3 standard sample (PE/EA=1/1, phosphomolybdic acid), and new spots with reduced polarity were observed. The reaction solution was evaporated under reduced pressure, and the obtained solid was dissolved in ultra-dry dichloromethane (5 ml), and then added dropwise to a mixed solution of compound 1-(2-hydroxyethyl)-4-methylpiperazine (500 mg) and pyridine (10 mL). After the addition was completed, the reaction solution was stirred at 70°C for three hours. The solution was orange-yellow. TLC (DCM/MeOH/NH 4 OH=10/1/0.1, phosphomolybdic acid) showed that a new spot was generated below pyridine. An appropriate amount of silica gel and dichloromethane were added to mix the sample and purified (10 g normal phase column, DCM:DCM/MeOH/NH 4 OH, 0-0% 5 min, 0-70% 20 min, 70-70% 10 min, flow rate 20 ml/min) to obtain a light yellow oily liquid compound 1 (200 mg, 47% yield).

The synthetic route of compound 14 is as follows:

步骤1：Step 1:

将化合物1-1(1.0g)溶于DCM(20ml)，室温搅拌，依次称取1-乙基-(3-二甲基氨基丙基)碳酰二亚胺盐酸盐(EDCI，2.47g)，4-二甲氨基吡啶(DMAP，524mg),三乙胺(1.30g)和(8Z,11Z)-十七碳-8,11-二烯-1-醇(2.16g)分批加入反应体系，室温搅拌16h。取少量反应液稀释与1-1标样对照点板(PE/EA＝10/1，磷钼酸和溴甲酚绿)，观察到极性变小的新点。反应液加水淬灭，分液，有机相减压蒸发，加适量硅胶拌样、纯化(80g正相柱，PE/EA，0-0％5min，0-10％20min，10-10％10min，流速40ml/min)，点板监测，将纯产物部分馏分蒸发，得到无色油状液体化合物14-1(2.1g，69.8％收率)。Compound 1-1 (1.0 g) was dissolved in DCM (20 ml), stirred at room temperature, 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDCI, 2.47 g), 4-dimethylaminopyridine (DMAP, 524 mg), triethylamine (1.30 g) and (8Z, 11Z)-heptadeca-8,11-diene-1-ol (2.16 g) were weighed in batches and added to the reaction system, stirred at room temperature for 16 h. A small amount of the reaction solution was diluted with the 1-1 standard sample control plate (PE/EA=10/1, phosphomolybdic acid and bromocresol green), and new spots with reduced polarity were observed. The reaction solution was quenched with water, separated, and the organic phase was evaporated under reduced pressure. An appropriate amount of silica gel was added for sample mixing and purification (80 g normal phase column, PE/EA, 0-0% 5 min, 0-10% 20 min, 10-10% 10 min, flow rate 40 ml/min), and the plate was monitored. The pure product fraction was evaporated to obtain a colorless oily liquid compound 14-1 (2.1 g, 69.8% yield).

步骤2：Step 2:

向化合物14-1(2.1g)的二氯甲烷溶液(20ml)溶液中加入三氟乙酸(5ml)。将混合物在室温下搅拌16小时。TLC显示化合物14-1完全消失，有一个极性变大的点生成。将反应液旋干，加入饱和碳酸氢钠水溶液(100ml)淬灭多余的三氟乙酸，乙酸乙酯(100ml×2)萃取，有机相经无水硫酸钠干燥，过滤，浓缩后，加适量硅胶和DCM拌样、纯化(80g正相柱，PE/EA，0-0％5min，0-50％20min，50-50％min，流速50ml/min)得到无色油状化合物14-2(2.1g，88.9％收率)。Trifluoroacetic acid (5 ml) was added to a dichloromethane solution (20 ml) of compound 14-1 (2.1 g). The mixture was stirred at room temperature for 16 hours. TLC showed that compound 14-1 completely disappeared and a point with increased polarity was generated. The reaction solution was spin-dried, saturated sodium bicarbonate aqueous solution (100 ml) was added to quench the excess trifluoroacetic acid, and ethyl acetate (100 ml × 2) was used for extraction. The organic phase was dried over anhydrous sodium sulfate, filtered, concentrated, and added with appropriate amount of silica gel and DCM to mix the sample and purify (80 g normal phase column, PE/EA, 0-0% 5 min, 0-50% 20 min, 50-50% min, flow rate 50 ml/min) to obtain colorless oily compound 14-2 (2.1 g, 88.9% yield).

A small amount of the reaction solution was taken and spot-plated with a 14-2 standard sample (PE/EA=1/1, phosphomolybdic acid), and new spots with reduced polarity were observed. The reaction solution was evaporated under reduced pressure, and the obtained solid was dissolved in ultra-dry dichloromethane (5 ml), and then added dropwise to a mixed solution of compound 1-(2-hydroxyethyl)-4-methylpiperazine (500 mg) and pyridine (10 ml). After the addition was completed, the reaction solution was stirred at 70°C for three hours. The solution was orange-yellow. TLC (DCM/MeOH/NH 4 OH=10/1/0.1, phosphomolybdic acid) showed that a new spot was generated. An appropriate amount of silica gel and dichloromethane were added to mix the sample and purified (10 g normal phase column, DCM:DCM/MeOH/NH 4 OH, 0-0% 5 min, 0-70% 20 min, 70-70% 10 min, flow rate 20 ml/min) to obtain a light yellow oily liquid compound 14 (160 mg, 41.6% yield).
