This Molecule Was Designed On The Basis Of X-Ray Structure Of The Complex Of D-Myo-Inositol 1,3,4,5-Tetrakisphosphates,Ins(1,3,4,5)P-4,And Grp1 Ph (General Receptor Of Phosphoinositides Pleckstrin Homology) Domain For The Application To The Widely Employed Biotin-Avidin Techniques. The Building Block Of Inositol Moiety Was Synthesized Starting With Myo-Inositol And Assembled With The Biotin-Linker Moiety Through A Phosphate Linkage. The Equilibrium Dissociation Constant K-D Of Biotinylated Ins(1,3,4,5)P-4 Binding Of Original Grp1 Ph Domain Was 0.14 Mu M In Pull-Down Analysis,Which Was Comparable To That Of Unmodified Ins(1,3,4,5)P-4. Furthermore,Biotinylated Ins(1,3,4,5)P-4 Had An Ability To Distinguish Grp1 Ph Domain From Plc Delta(1) Ph Domain. Thus,Biotinylated Ins(1,3,4,5)P-4 Retained The Binding Affinity And Selectivity Of Original Grp1 Ph Domain,And Realized The Intracellular Ins(1,3,4,5)P-4 Despite A Tethering At The 1-Phosphate Group Of Inositol.

专利号:US-11938187-B2 优先权日:2021-06-10 标题:Methods and compositions for synthesis of two-photon cleavable phosphoramidite molecules for oligonucleotide conjugation 发明人:LO PEGGY PIK KWAN; LIU LING SUM; TAM DICK YAN 权利人:UNIV CITY HONG KONG 摘要:The syntheses of two phosphoramidite building blocks based on BNSF and BNSMB structures are disclosed. Furthermore, some common molecular intermediates have been designed and linked to the central biphenyl core of the two molecules, resulting in a versatile and cost-effective design. These compounds can be effectively introduced to DNA oligonucleotides via the well-established standard cyanoethylphosphoramidite chemistry on the nucleic acid synthesizer. Fragmentation of these BNSF- and BNSMB-functionalized DNA strands is achieved by both one-photon and two-photon photolysis of photoliable bonds of [2-(2-nitrophenyl)propoxy]carbonyl groups on BNSF and BNSMB molecules respectively, resulting in two short pieces of single-stranded DNAs. The versatile design and facile synthesis of these two-photon photocleavage phosphoramidite molecules are beneficial to synthetic chemists and photochemists for the development of new caged compounds which enables to introduce into oligonucleotides as light-triggered carriers via solid-phase synthesis for a wide range of applications in materials science, polymer, chemistry, biology and DNA nanoecthnology.
专利号:US-2024092821-A1 优先权日:2020-03-31 标题:Synthesis of oligonucleotides and related compounds 发明人:ZHONG MINGHONG; JIN YI; GALA DINESH; PRHAVC MARIJA 权利人:JANSSEN BIOPHARMA INC 摘要:Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide subunit on a cleavable support having an azidomethyl moiety and a nucleoside phosphoramidite or an oligonucleotide phosphoramidite, capping, oxidation/thiolation and deblocking; followed by orthogonal cleavage of the azidomethyl support while keeping all other protecting groups intact. The method can be used in combination with a support moiety for either solid phase or liquid phase oligo synthesis. The soluble support facilitates homogeneous reactions and efficient separations by simple precipitation. The methods also provide novel intermediates useful in the synthesis of oligonucleotide conjugates.
