A novel method to synthesize cyclic oligonucleotides (5- to 26-mer) using the thiol-maleimide reaction is described. The target molecules were obtained after subsequent removal of thiol and maleimide protecting groups from 5'-maleimido-3'-thiol-derivatized linear precursors. Retro-Diels-Alder conditions deprotecting the maleimide simultaneously promoted cyclization cleanly and in high yield.

In this communication, we report on a new route to the functionalization of ATRP polymers exploiting their halide end-groups, which were converted successfully into reactive disulfide end-groups, using sodium methanethiosulfonate. The resultant disulfide-terminated polymers could then be reacted with different functional thiols to yield functional polymers exploiting either thiol/disulfide exch...

background & aim: free radicals are produced in ischemic processes. nerve damage caused by free radicals may play a role in neurological diseases and antioxidants are protective activity. ellagic acid is a polyphenol compound with antioxidant properties which is found in fruits like pomegranate, blackberry, and all types of mulberry. this study aimed to evaluate the effect of 14 days of ora...

Objective: The main objective of this study was to compare the effects minimal and high gas flow-controlled hypotension applications on IMA thiol/disulfide balance, which are indicators oxidative stress.Methods: Patients undergoing elective tympanoplasty were randomized two groups as minimal-flow high-flow anesthesia groups. Minimal flow performed with 5L/min fresh reduced 0.4 L/min. High admin...

Thiol-ene photopolymerizations gain a growing interest in academic research. Coatings and dental restoratives are interesting applications for thiol-ene photopolymerizations due to their unique features. In most studies the relative flexible and hydrophilic ester derivative, namely pentaerythritoltetra(3-mercaptopropionate) (PETMP), is investigated as the thiol component. Thus, in the present s...

There is a worldwide race to convert waste heat useful energy using thermoelectric materials. Molecules are attractive candidates for thermoelectricity because they can be synthesised with the atomic precision, and intriguing properties due quantum effects such as interference induced at room temperature. also expected show low thermal conductance that needed enhance performance of Recently, te...

Radical-mediated thiol-yne step-growth photopolymerizations are utilized to form highly cross-linked polymer networks. This reaction mechanism is shown to be analogous to the thiol-ene photopolymerization; however, each alkyne functional group is capable of consecutive reaction with two thiol functional groups. The thiol-yne reaction involves the sequential propagation of a thiyl radical with e...

Background: Parkinson's disease is one of the prevalent degenerative diseases of the neural system. Oxidative stress, which has been recognized as the most important factor of Parkinson's disease, plays a main role in the death of neurons in this disease. Antioxidants have a proved role in the prevention of oxidative stress. Objective: Considering the presence of evidence regarding antioxid...

Maleimide-functionalised Pt(IV) complexes with highly selective binding properties to thiol groups were synthesised as precursors for binding of thiol-containing tumour-targeting molecules like human serum albumin.
