摘要:This invention relates a process for preparing octreotide and derivatives thereof. The starting material, Cys(Trt)-2-Chlorotrityl resin is coupled with various amino acids to obtain a protected heptapeptide of formula (2): Boc-D-Phe-Cys(Trt)-Phe-D-Trp-Lys(Boc)-Thr(OBut)-Cys(Trt)-2-Chlorotrityl resin. The linear protected peptide of formula (2) is cleaved from the support using TFA5TIS and water to yield linear protected peptide of formula (3) Boc-D-Phe-Cys(Trt)-Phe-D-Trp-Lys(Boc)-Thr(OBut)-Cys(Trt)-OH Linear protected heptapeptide of formula (3) is deprotected to yield heptapeptide of formula (6): D-Phe-Cys-Phe-D-Tip-Lys-Thr-Cys-OH; which is cyclized using hydrogen peroxide and to the cyclic peptide of formula (7) D-Phe-Cys-Phe-D-Trp-Lys-Thr-Cys-OH; threoninol is coupled at C terminal to yield octreotide. Alternatively threoninol is coupled to the heptapeptide of formula (3) to yield protected octapeptide of formula (4) Boc-D-Phe-Cys(Trt)-Phe-D-Trp-Lys(Boc)-Thr(OBut)-Cys(Trt)-Thr-OL which is subsequently deprotected to yield linear octapeptide of formula (5) D-Phe-Cys-Phe-D-Trp-Lys-Thr-Cys-Thr-OL and cyclized with hydrogen peroxide to yield cyclic octreotide with a yield of >95%.

摘要:Ternary and quaternary Chalcopyrite CuInxGa1-xSySe2-y (CIGS, where 0≰x and y≰1) nanoparticles were synthesized from molecular single source precursors (SSPs) by a one-pot reaction in a high boiling solvent using salt(s) (i.e. NaCl as by-product) as heat transfer agent via conventional convective heating method. The nanoparticles sizes were 1.8 nm to 5.2 nm as reaction temperatures were varied from 150° C. to 190° C. with very high-yield. Tunable nanoparticle size is achieved through manipulation of reaction temperature, reaction time, and precursor concentrations. In addition, the method developed in this study was scalable to achieve ultra-large quantities production of tetragonal and quaternary Chalcopyrite CIGS nanoparticles.
