标题:Synthesis of polynucleotides having random sequences
发明人：NEUNER PHILIPPE
权利人:ISTITUTO DI RICERCHE DI MOLECO
摘要:Subject of this invention is a process for the chemical synthesis of polynucleotides having totally or partially random sequences, based on the utilization, as synthesis monomer units for the random sequence part, or presynthesized mononucleotides and dinucleotides. Said synthesis is carried out on separate supports, so that on each of those supports is alternated at least one reaction cycle wherein a mixture of said dinucleotides is bound, with at least one reaction cycle wherein a mononucleotide is bound, and that in a preferred embodiment at the end of the n cycles required for a codon synthesis, the supports are mixed and then redivided into one or more reaction containers. The resulting polynucleotides are such that, for the random sequence part, each trinucleotide unit is fit to match only a limited number of codons, predefined for each unity in number and sequence, and the genetic code degeneracy effects can thus be eliminated. FIG. 1 shows the chemical structure of the dinucleotides utilized as monomer units for the synthesis of codons forming the final sequence.

标题:Synthesis of cyclic peptides
发明人：LIU JUN; DAI XUEDONG; SU ZHUANG
摘要:The cyclic pentapeptide cyclo(-Arg-Gly-Asp-D-Phe-Lys-) is a highly potent and selective inhibitor for the α v β 3 integrin. A related compound, cyclo(-Arg-Gly-Asp-D-Phe-Val-), is a promising anticancer drug candidate; it has been found to inhibit angiogenesis and induce apoptosis in vascular cells. We have developed a synthesis of arginine containing cyclic peptides using the cyclizcation reagent 1-propanephosphonic acid cyclic anhydride (T3P) and the guanidine protecting group, 2,2,5,7,8-pentamethylchroman-6-sulfonyl (Pbf). This improved synthesis is environmentally friendly and is generally applicable to the synthesis of other cyclic peptides.

标题 :Computer implemented method for engineering fluorinase enzymes for synthesis of fluorophenyl compounds

摘要:The present invention discloses a computer-implemented method for engineering fluorinase enzymes towards the synthesis of fluorophenyl compounds. Limited or no mechanistic details of fluorinase enzymes have hindered progress in understanding their catalytic mechanisms for synthesizing synthetic organofluorine compounds. Through a comprehensive computational screening process, specific methionine-sulfonium phenyl substrates, including [(3S)-3-amino-3-carboxypropyl][2,5-difluoro-4-(4-methoxy-2,4-dioxobutyl)phenyl]methylsulfonium, were designed and optimized using quantum chemical optimization techniques. This methodology uncovers crucial information on F— ion attack conformation and the catalytic mechanism of the substrate, leading to the formation of Methyl 3-oxo-4-(2,4,5-trifluorophenyl)butanoate. Furthermore, a protein sequence and 3D modeling-based enzyme screening process was employed to identify the most suitable enzyme for this substrate. The identified enzyme was then engineered using the mechanistic insights gained from the studies, resulting in improved substrate scope, stability and catalytic efficiency. This computer-based approach offers an efficient and precise alternative to traditional trial-and-error methods, advancing the field towards the successful synthesis fluorophenyl compounds.
