Equilibrium dialysis has been used to demonstrate that vincristine (VCR), vinblastine (VLB) and colchicine (CLC) adsorb to serum proteins. In addition, there is about 19 per cent more binding of CLC to plasma than serum. The extent of adsorption for all three alkaloids is approximately proportional to both the free alkaloid concentration and the serum protein concentration, with no evidence of saturation at the concentrations used. At physiologic concentrations of protein, the per cent of drug bound to serum protein is about 75 per cent for VLB and VCR and 50 per cent for CLC, indicating that the drugs are not tightly bound, and that there is no impediment to rapid extravascular distribution. On a mole per g basis, VLB and VCR adsorb ten times more extensively to commercially obtained α- and β-globulins than to albumin or γ-globulin. CLC binds nonselectively to these components.  相似文献

Mechanism of interaction of antidiabetic drugs, repaglinide and gliclazide, to human serum albumin has been studied using fluorescence spectroscopic technique. Repaglinide had much higher affinity for human serum albumin when compared with gliclazide. The order of association constants was 10(5) for both the drugs. The size, hydrophobicity and flexibility of the drug molecules play a major role in explaining the binding behaviour of these drugs. Hydrophobic interactions are predominantly involved in the binding. However, drugs do not share common sites with 1-anilinonaphthalene-8-sulphonate on the human serum albumin molecule. Both tyrosine and tryptophan residues participate in the interaction. Repaglinide and gliclazide are bound to site II on the human serum albumin molecule, and the aromatic ring of 411Tyr appears to be involved in binding within site II. Although they do not bind at site I, their binding at site II may cause conformational changes thereby affecting the binding of other ligands to site I. Site-specificity can be useful in predicting the competitive displacement of these drugs by other co-administered drugs, resulting in fluctuations of the blood glucose levels in diabetic patients. Stern-Volmer analysis of quenching data indicated that the tryptophan residues are not fully accessible to the drugs and predominantly dynamic quenching mechanism is involved in the binding.  相似文献

A novel series of substituted sulfanyldihydroimidazolones (1) that modulates high-density lipoprotein cholesterol (HDL-C) has been reported to have HDL-elevating properties in several animal models. Concerns about the chemical and metabolic stability of 1 directed us to explore the structure-activity relationship (SAR) of a related series of substituted thiohydantoins (2). Expansion of the scope of the thiohydantoin series led to exploration of compounds in related thio-containing ring systems 3-7 and the N-cyanoguanidine derivative 8. Compounds were tested sequentially in three animal models to assess their HDL-C elevating efficacy and safety profiles. Further evaluation of selected compounds in a dose-response paradigm culminated in the identification of compound 2.39 as a candidate compound for advanced preclinical studies.  相似文献

OBJECTIVES: To compare the accuracy of the classification of the degree of decrease in glomerular filtration rate (GFR), measured exactly (as inulin clearance) on the basis of serum concentrations of creatinine (Scr), cystatin C (Scyst) and creatinine clearance predicted according to Cockcroft and Gault (CG), and to establish whether any of the above methods is more accurate than the other 2. SUBJECTS: The study was conducted in 126 patients (52 men, 74 women) aged 18 to 64 years with various chronic renal diseases (predominantly various forms of glomerulonephritis and tubulointerstitial nephritis). The study subjects were divided into 3 subgroups according to GFR levels. Subgroup A (n = 41) included individuals with GFR >50 ml/min/1.73 m2, subgroup B (n = 56) was made up by individuals with GFR of 20-50 ml/min/1.73 m2, while subgroup C (n = 29) comprised individuals with GFR <20 ml/min/1.73 m2. METHODS: GFR was determined on the basis of renal inulin clearance (Cin) under conditions of stable plasma levels and water loading. Each individual had his/her Scr, Scyst values measured and CG was calculated. Results were evaluated using discrimination analysis. RESULTS: Mean values and SD of the monitored markers in the subgroups were as follows. Subgroup A: Scr 102.4 (38.3) micromol/l, Scyst 1.46 (0.42) mg/l, CG 80.0 (19.2) ml/min/1.73 m2. Subgroup B: Scr 161.2 (45.6) micromol/l, Scyst 2.01 (0.55) mg/l, CG 46.1 (16.7) ml/min/1.73 m2. Subgroup C: Scr 314.9 (58.3) micromol/l, Scyst 3.41 (0.96) mg/l, CG 24.8 (7.6) ml/min/1.73 m2. The percent of correct classifications and the respective confidence intervals (95%) for the methods used were as follows. Subgroup A: Scr 79.3 (64.6, 94.0), Scyst 75.9 (60.3, 91.5), CG 86.2 (73.6, 98.8). Subgroup B: Scr 51.8 (35.5, 68.1), Scyst 57.1 (41.5, 72.7), CG 64.3 (48.6, 80.0). Subgroup C: Scr 90.2 (81.0, 99.2), Scyst 80.5 (68.1, 92.9), CG 87.8 (77.8, 97.8). The percent of correct classifications established on the basis of Scr, Scyst and CG in subgroup B is significantly lower than that of correct classifications in subgroups A and C (p < 0.05-0.001). The percent of correct classifications using Scr, Scyst and CG, estimated separately for each subgroup (A, B, C) does not differ significantly. CONCLUSIONS: The findings support the assumption that estimation of the decrease in GFR using Scr, Scyst and CG is, as regards their utilization in everyday practice, suitable for individuals with severely decreased GFR (<20 ml/min/1.73 m2) and for individuals with a decrease in GFR to levels >50 ml/min/173 m2. Estimation of the decrease in GFR using the above subgroups did not demonstrate significant differences among Scr, Scyst and CG. Using the above markers, estimation of the decrease in GFR is the least reliable with GFR values in the range of 20-50 ml/min/1.73 m2.  相似文献
