D-型氨基酸是目前许多新型抗生素、抗病毒等药物的中间体,国外对此类化合物的制备技术出口进行限制,国内外对此类产品需求量大,我国每年进口大量D-氨基酸用于新药生产中。
本技术开发的品种有D-半胱氨酸、D-苯丙氨酸、D-丝氨酸、D-组氨酸、D-脯氨酸、D-缬氨酸,D-色氨酸。 我方开发的D-型氨基酸制备技术是采用原料来源于天然的L-型氨基酸,通过自主开发的反应工艺和转型剂,使其L-型氨基酸转化为D-型氨基酸。产物D-型氨基酸,光学纯度高,部分产品已应用合成抗生素(如头孢米诺钠)试验,完全可替代进口产品。生产工艺绿色化轻微污染,成本低,有可观的经济效益和重要的社会效益。 目前有两个品种D-半胱氨酸和D-苯丙氨酸技术已完成中试(500L 釜试验),产品有市场。
二、应用范围和生产条件:
D-型氨基酸具有天然氨基酸所不具备的优良性能,在药物合成(医药和农药)、食品、饲料等方面具有广泛的用途。其次在化妆品、生化试剂领域也有应用价值。
1、在医药领域应用;如 D-半胱氨酸是头孢米诺钠的重要中间体;D-苯丙氨酸是糖尿病药物纳格列那的中间体。D-型氨基酸还用于合成治疗老年痴呆症药物;合成肽类抗疼止痛药;用于肿瘤治疗;制备人体激素类似物;制备生长激素IL-1抑制剂;合成直接刺激垂体分泌生长激素的肽类促进剂;合成抑制神经紧张药物;用于角膜切除手术等。
2、在食品领域:各种D-氨基酸构成的二肽或者短肽,它们甜度高,安全,无热量,既适合普通人群消费,更适合肥胖、糖尿病人消费。
3、在化妆品领域:国外越来越多的非天然氨基酸用于化妆品中。
4、生化试剂领域:氨基酸是人类永恒的研究主题,因此需要大量的各种氨基酸衍生物。 (含环保要求)年产30吨D-氨基酸系列产品,其生产线为一个通用的精细化工生产线,主要设备为标准设备,部分设备为非标设备。
5、 公用工程:需生产厂房6M高以上,有水、电、低压蒸汽。 设备:搪瓷釜、不锈钢釜、冷凝器、离心机等。 D-氨基酸项目绿色化工艺,有轻微污染物。产生少量废液和废固体物可焚烧。
技术特性: D-型氨基酸制备技术是采用原料来源于天然的L-型氨基酸为原料,通过自主开发的反应工艺和转型剂,使其L-型氨基酸转化为D-型氨基酸。产物D-型氨基酸,光学纯度高,制备技术居国内领先水平。工艺流程简单,装置投资少,生产成本低,经济和社会环保效益显着。 D-半胱氨酸,D-苯丙氨酸中试已完成。
市场及经济效益预测 规模与投资:
年产30吨D-氨基酸 固定及无形资产投资:350万元;  流动资金:250万元;  投资合计:600万元
三、提供技术的程度和合作方式:
D-半胱氨酸,D-苯丙氨酸中试已完成,
技术转让,转让费视品种协商,实行交钥匙工程等多种形式合作。
