Reaxys Award 2017: tre ricerche italiane premiate da Elsevier

Tre giovani soci della SCI sono stati premiati da Elsevier per la stesura di un saggio scientifico sulla loro attività di ricerca, coadiuvata dal database Reaxys. Si tratta di un prestigioso riconoscimento internazionale, giunto alla sua terza edizione, promosso dal Gruppo Giovani della SCI insieme al principale editore scientifico mondiale

Proceedings of the Merck Young Chemists’ Symposium XIX edition

Welcome to the 19th edition of the Merck Young Chemists’ Symposium (MYCS), formerly also known as SAYCS and MEYCS. This event is organized by the Young Group of Società Chimica Italiana (SCI Giovani) with the financial support from Merck and several other sponsors, that you will meet during the conference. The symposium covers all the disciplines of Chemistry, aiming to connect young researchers, inspire new ideas, and potentially trigger new collaborations. MYCS is an international event, thanks to the leading role of SCI into the European framework, the support from the European Young Chemists’ Network (EYCN), and most importantly to all of you, participants coming from 9 countries from all over the world. This year we are honored to have the exceptional number of 240 participants. Thank you for the great trust shown towards SCI Giovani, Merck and all our supporters. The contributions of our 4 invited plenary speakers will just be the icing on the cake of a wonderful scientific event I truly hope you will all enjoy with us.

UV-light-driven prebiotic synthesis of iron–sulfur clusters

Iron–sulfur clusters are ancient cofactors that play a fundamental role in metabolism and may have impacted the prebiotic chemistry that led to life. However, it is unclear whether iron–sulfur clusters could have been synthesized on prebiotic Earth. Dissolved iron on early Earth was predominantly in the reduced ferrous state, but ferrous ions alone cannot form polynuclear iron–sulfur clusters. Similarly, free sulfide may not have been readily available. Here we show that UV light drives the synthesis of [2Fe–2S] and [4Fe–4S] clusters through the photooxidation of ferrous ions and the photolysis of organic thiols. Iron–sulfur clusters coordinate to and are stabilized by a wide range of cysteine-containing peptides and the assembly of iron–sulfur cluster-peptide complexes can take place within model protocells in a process that parallels extant pathways. Our experiments suggest that iron–sulfur clusters may have formed easily on early Earth, facilitating the emergence of an iron–sulfur-cluster-dependent metabolism
