胰岛素治疗的最终目标是使其进入人体后能够模拟生理胰岛素分泌,从而严格控制血糖,减少糖尿病各种并发症的发生。而胰岛素类似物与其他类型的胰岛素相比,作用更接近生理胰岛素[1]。本文就近年来这方面的发展综述如下。1速效胰岛素类似物1.1赖脯胰岛素(insulin lispro,IL)商品名 相似文献

前言
自从1921年胰岛素应用于临床以来,经过多年的发展,胰岛素可以应用于临床各种类型糖尿病的治疗,是否需要使用取决于胰岛素抵抗和内源性胰岛素分泌之间的平衡,所有没有进行胰岛移植或者胰腺移植的1型糖尿病患者均需要胰岛素治疗; 相似文献

双时相胰岛素类似物在胰岛素强化治疗中的应用 总被引:2,自引:0,他引:2
传统胰岛素强化治疗能产生近似生理性的胰岛素分泌,但多次皮下注射给患者带来不便,依从性差.新的双时相胰岛素类似物因同时预混有速效胰岛素和鱼精蛋白化的部分,因此能够更好地控制空腹和餐后血糖,为胰岛素强化治疗提供了新方案. 相似文献

The Mechanism of Protraction of Insulin Detemir,a Long-Acting,Acylated Analog of Human Insulin 总被引:3,自引:0,他引:3

PURPOSE: Insulin detemir has been found in clinical trials to be absorbed with very low variability. A series of experiments were performed to elucidate the underlying mechanisms. METHODS: The disappearance from an injected subcutaneous depot and elimination studies in plasma were carried out in pigs. Size-exclusion chromatography was used to assess the self-association and albumin binding states of insulin detemir and analogs. RESULTS: Disappearance T50% from the injection depot was 10.2+/-1.2 h for insulin detemir and 2.0+/-0.1 h for a monomeric acylated insulin analog. Self-association of acylated insulin analogs with same albumin affinity in saline correlated with disappearance rate and addition of albumin to saline showed a combination of insulin detemir self association and albumin binding. Intravenous kinetic studies showed that the clearance and volume of distribution decreased with increasing albumin binding affinity of different acylated insulin analogs. CONCLUSIONS: The protracted action of detemir is primarily achieved through slow absorption into blood. Dihexamerization and albumin binding of hexameric and dimeric detemir prolongs residence time at the injection depot. Some further retention of detemir occurs in the circulation where albumin binding causes buffering of insulin concentration. Insulin detemir provides a novel principle of protraction, enabling increased predictability of basal insulin. 相似文献

Effects of Phenol and meta-Cresol Depletion on Insulin Analog Stability at Physiological Temperature
《Journal of pharmaceutical sciences》2014,103(8):2255-2267
The stability of three commercial “fast-acting” insulin analogs, insulin lispro, insulin aspart, and insulin glulisine, was studied at various concentrations of phenolic preservatives (phenol and/or meta-cresol) during 9 days of incubation at 37°C. The analysis by both size-exclusion and reversed-phase chromatography showed degradation of lispro and aspart that was inversely dependent on the concentration of phenolic preservatives. Insulin glulisine was much more stable than the other analogs and showed minimal degradation even in the absence of phenolic preservatives. With sedimentation velocity ultracentrifugation, we determined the preservatives' effect on the insulins' self-assembly. When depleted of preservatives, insulin glulisine dissociates from higher molecular weight species into a number of intermediate molecular weight species, in between monomer and hexamer, whereas insulin aspart and insulin lispro dissociate into monomers and dimers. Decreased stability of insulin lispro and insulin aspart seems to be because of the extent of dissociation when depleted of preservative. Insulin glulisine's dissociation to intermediate molecular weight species appears to help minimize its degradation during incubation at 37°C. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 103:2255–2267, 2014 相似文献

Purpose. To study the effect of mechanical grinding on crystallinity changes of naproxen (NAP) in mixtures with -cyclodextrin (Cd), amorphous Cd, and maltohexaose (M6); and the possible formation of a pseudo-inclusion complex between NAP and M6 in aqueous solution.
Methods. NAP-additive physical mixtures at 0.30,0.18, and 0.10 mass fraction of drug were tested, after increasing grinding times, by differential scanning calorimetry (DSC) and X-ray powder diffractometry (XRD). Interaction in aqueous solution was examined by phase-solubility and fluorescence analyses supported by molecular modelling.
Results. In the mixtures with each additive the fusion enthalpy per unit mass of NAP decreased and the half width at half maximum of selected X-ray diffraction peaks of NAP increased with the progress of grinding time following the loss of crystallinity of the samples. The mechanical treatment apparently did not affect the chemical integrity of the drug. Particularly active in the equimolar mixture was the best amorphizing agent, M6. Solution studies and molecular modelling confirmed M6 may have the feature of a supermolecule for NAP, which forms a 1:1 pseudo-inclusion complex that was as stable as the true inclusion complex with Cd.
Conclusions. The intrinsically amorphous linear analog of Cd might be a potential amorphism-inducing agent and solubilizer for scarcely water soluble drugs. 相似文献

Purpose
Bcr-Abl, the causative agent of chronic myelogenous leukemia (CML), localizes in the cytoplasm where its oncogenic signaling leads to proliferation of cells. If forced into the nucleus Bcr-Abl causes apoptosis. To achieve nuclear translocation, binding domains for capture of Bcr-Abl were generated and attached to proteins with signals destined for the nucleus. These resulting proteins would be capable of binding and translocating endogenous Bcr-Abl to the nucleus. 相似文献20.
