We have studied the disassembly and assembly of two morphologically and functionally distinct parts of the Golgi complex, the cis/middle and trans cisterna/trans network compartments. For this purpose we have followed the redistribution of three cis/middle- (GMPc-1, GMPc-2, MG 160) and two trans- (GMPt-1 and GMPt-2) Golgi membrane proteins during and after treatment of normal rat kidney (NRK) c...
در این تحقیق روشی جهت سنتز یک سری از کمپلکس های پلاتین(ii)، حاوی لیگاندهای دهنده ی فسفری شامل فسفیت و فسفین ارائه شده است. واکنش پیش ماده ی پلاتین (ii)، cis,cis-[me2pt(?-sme2)2ptme2]، با 2 اکی مولار از لیگاند p(oph)3در استون و پس از آن افزودن 2 اکی مولار از لیگاند l،pph3, 4-mepy l= به ترتیب کمپلکس های 1، cis-[me2pt{p(oph)3}(pph3)] و 2، cis-[me2pt{p(oph)3}(4-mepy)] را تولید می نماید. واکنش ci...
The chaperonins GroEL and GroES are essential mediators of protein folding. GroEL binds nonnative protein, ATP, and GroES, generating a ternary complex in which protein folding occurs within the cavity capped by GroES (cis-cavity). We determined the crystal structure of the native GroEL-GroES-ADP homolog from Thermus thermophilus, with substrate proteins in the cis-cavity, at 2.8 A resolution. ...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Fenestranes are an intriguing class of highly strained molecules possessing a quaternary carbon with bonds that deviate from the canonical tetrahedral geometry. Herein we report the discovery that the natural product pleuromutilin can be used as a structurally complex starting material for the synthesis of a series of bridged cis,cis,cis,cis-[4.5.5.5]- and cis,cis,cis,cis-[4.5.7.5]oxafenestrane...
چکیده واکنــش کمپــلکس cis-[ptcl2(pph3)2] با پتاســیم هالید (هالید= برومید، یدید) در حلال استن منجــر به واکنش تبادل هالوژن گردیــد و کمپلکس های, (x = br, i) [ptx2(pph3)2] تشکــیل شـدند. همچنین واکنــش کمپلــکس cis-[ptcl2(pph3)2] و قلــع(ii) برومید با نسبـــت مولی 1:2 pt:kbr / در مخلــوط حلالــهای دی کلرومتان/ تتراهیــدروفوران منجر به تبادل هالــوژن گردید و مخلوط کمپلکسهای cis, trans-[ptbr...
background: tumor response after multimodality treatment using combination of radiation, chemotherapeutic drugs and hyperthermia usually assessed by parameters such as tumor growth delay, volume doubling time and regression response. the study herein was conducted to investigate the usefulness of micronucleus assay for assessing the multimodality treatment. materials and methods: the induction ...
The kinetics of the ruthenium-promoted cis,cis to trans,trans isomerization of 1,1,2,2,5,5,6,6-octamethyl-1,2,5,6-tetrasilacycloocta-3,7-diene were investigated. Incubation of a ruthenium alkylidene complex, (Cy(3)P)RuCl(2)(==CHPh)Ru(p-cymene)Cl(2), in CD(2)Cl(2) for 5 days at 40 degrees C afforded a catalytically active ruthenium species that was shown to be responsible for promoting the isome...
