Sugar Derivatives TRIZ Cases

Controlled hydrogenation, deprotection, and CIDT crystallization produce up to 99.9% pure difluorotetrahydrouridine.

This case uses sugar-derivative prodrugs and intracellular glycosidase activity to reduce toxicity to non-senescent cells.

Controlled roller grinding drives solid-solid cellulose hydrolysis, raising sugar yield while limiting energy use and byproduct formation.

2′-Deoxy-2′-fluoro-2′-C-methyl nucleotides improve dsRNA stability, silencing activity, and on-target specificity.

Cleavable antibody linkers deliver camptothecines to tumor markers, improving therapeutic index while limiting normal-tissue exposure.

This case uses viral delivery of ASPA to convert NAA into AcCoA, supporting ATP synthesis and neuronal resistance to oxidative stress.

This case uses cleavage, hairpin formation, and distinct melting temperatures to detect multiple nucleic acid targets with one fluorophore.

This case uses miR-451 shRNA mimics and AGO2 catalysis to bypass DICER, generating one active strand for more specific silencing.

Deamination, probe hybridization, and machine learning profile methylation markers for colon cancer diagnosis and monitoring.

This case uses organic borane to convert oxidized 5mC to DHU, reducing DNA degradation and false positives during sequencing.

This case uses palatable liquid ASBTI formulations to reduce bile acid recycling and support pediatric cholestatic liver treatment.

Targeted primers and PCR replace lengthy culture methods, improving Mycobacterium DNA detection sensitivity and specificity.

Synthetic sialylated glycan electrodes use impedance changes to detect and differentiate neuraminidases without labeled substrates.

A hydrophobic, photolabile terminal tag enables mild photocleavage and cleaner purification of synthesized polynucleotides.

Bicyclic heterocycle conjugates improve GalNAc binding and internalization for targeted oligonucleotide delivery to hepatocytes.

CpG oligonucleotides and plasmids activate TLR21 to support non-specific defense.

This case uses recombinant enzymes to remove 3′-O-glycoside blocks, limiting DNA damage, signal decay, and phasing errors.

This case uses basic ion exchange resin and organic-acid elution to improve purity and concentration while reducing thermal degradation.

EDC/NHS activation improves aqueous oligonucleotide conjugation to polymer beads.

Synthetic cap analogs simplify mRNA capping while supporting translation and stability.

This case combines D-form polymerases with cleavable labeled nucleotides for high-throughput L-polynucleotide sequencing.

This case activates carboxy groups on polymer beads before amino-maleimide and diene-modified oligonucleotide coupling in water.

These linkers cleave below the solvent's redox potential, avoiding water electrolysis and enabling localized nucleotide cleavage.

A high-salt, low-pH buffer enables silica surfaces to co-isolate DNA, RNA, and proteins while reducing time and contamination.

Non-bridging phosphorodithioate linkages simplify oligonucleotide stereochemistry while supporting nuclease resistance, uptake, and potency.

This case uses non-leaching ionic polymers in membranes or solid supports to produce food-grade chemicals with easier separation.
