Amino/carboxyl tsev blocks (xws li 6-aminohexanoic acid) feem ntau yog siv los ua pawg txuas hauv peptide synthesis. 2. Cov Pab Pawg Ua Haujlwm-Modified Building Blocks

Cov tsev thaiv no yog siv los qhia lossis ua kom zoo rau cov pab pawg ua haujlwm tshwj xeeb los hloov kho cov haujlwm lossis solubility ntawm cov molecule. Piv txwv li:

Hydroxyl tsev blocks (xws li 2,3,4-trihydroxybenzaldehyde) yog siv los txhim kho kev sib txuas ntawm hydrogen.

Halogen tsev blocks (xws li bromobenzene) feem ntau yog siv nyob rau hauv kev sib txuas lus tom ntej (xws li Suzuki thiab Buchwald-Hartwig).

3. Stereochemically Tswj Lub Tsev Blocks

Hauv kev tsim tshuaj, stereochemistry cuam tshuam rau kev ua haujlwm, yog li cov tsev thaiv no tau siv los tswj hwm chirality. Piv txwv li:

Chiral amino acid derivatives (xws li L-proline derivatives) yog siv los tsim cov chaw chiral.

Optically ntshiab cyclohexane tsev blocks yog siv nyob rau hauv asymmetric syntheses.

III. Classification los ntawm Daim Ntawv Thov
1. Kev Tshawb Nrhiav Tshuaj Hauv Tsev Blocks

Cov tsev thaiv no feem ntau yog siv hauv kev tshawb nrhiav tshuaj me me, xws li:

Kinase inhibitor tsev blocks (xws li imidazopyridines) yog siv rau hauv kev txhim kho tshuaj tiv thaiv kab mob. G protein-coupled receptor (GPCR) ligand tsev blocks (xws li indoles) yog siv rau hauv cov tshuaj neurological.
2. Cov khoom siv Science Building Blocks

Hauv cov khoom siv ua haujlwm (xws li OLEDs thiab cov khoom siv fluorescent), molecular tsev blocks muab cov khoom tshwj xeeb optoelectronic. Piv txwv li:

Triarylamine tsev blocks yog siv nyob rau hauv cov organic teeb -emitting diodes (OLEDs).

Conjugated polymer tsev blocks (xws li thiophene derivatives) yog siv rau hauv cov khoom siv hluav taws xob.
3. Bioorthogonal Chemical Building Blocks

Cov tsev thaiv no yog siv rau kev sau npe tshwj xeeb lossis kev hloov kho hauv cov kab ke lom neeg. Piv txwv li:

Azide-alkyne click chemistry tsev blocks (xws li DBCO thiab ethanedioxide) yog siv rau hauv vivo imaging.

Biotin-avidin system tsim thaiv yog siv rau kev tshawb fawb txog kev sib cuam tshuam ntawm cov protein.
IV. Cov ntsiab lus

Molecular tsev blocks tuaj yeem muab faib ua ntau yam. Los ntawm cov qauv tshuaj mus rau daim ntawv thov scenarios, txhua lub tsev thaiv plays lub luag hauj lwm irreplaceable nyob rau hauv hluavtaws chemistry thiab tshuaj discovery. Nrog rau kev nce qib hauv combinatorial chemistry thiab AI- pab tsim tshuaj, hom thiab kev siv ntawm molecular tsev blocks txuas ntxiv nthuav dav, muab cov cuab yeej ntau ntxiv rau kev tshawb nrhiav tshuaj tshiab thiab cov ntaub ntawv tshawb fawb. Nyob rau hauv lub neej yav tom ntej, customized tsev blocks rau cov hom phiaj tshwj xeeb yuav dhau los ua kev tshawb fawb hotspot, ntxiv txhawb kev txhim kho ntawm precision chemistry.
