Nws tuaj yeem yaj ib feem ntawm shellac, dewaxed dama resin, glycerin trirosin ester, roj paj rwb, thiab lwm yam.

2. Cov khoom siv tshuaj lom neeg: Cov tshuaj tiv thaiv dav dav ntawm ketones. Nws reacts nrog diphosphorus pentasulfide los tsim 2, 5-dimethylthiophene. 2, 5-dimethylpyrrole yog tsim thaum nws raug reacted nrog cov kua cawv-ammonia lossis cua sov nrog ammonium carbonate. Dehydration tsim 2, 5-dimethylfuran. Nws reacts nrog 2, 4-dinitrophenylhydrazine los tsim bis (2, 4-dinitrophenyl) hydrazone nrog lub ntsiab lus yaj ntawm 257 ° C.

3. Nws muaj nyob rau hauv cov nplooj luam yeeb thiab cov pa luam yeeb uas kho tau los ntawm cov pa luam yeeb.

4. Tshuaj txhawb zog hauv zos, qhov concentration siab ua rau muaj tshuaj loog.

2,5-Hexanedione ua haujlwm ua lub hauv paus tseem ceeb thiab yog cov khoom siv tseem ceeb hauv kev tsim tshuaj niaj hnub no. Nws cov qauv diketone symmetrical, muaj ob pawg carbonyl reactive, ua rau nws yog ib qho tseem ceeb rau kev tsim cov tshuaj heterocyclic thiab cyclic uas muaj ntau yam khoom xyaw tshuaj (APIs).

Nws cov ntawv thov tshuaj tseem ceeb suav nrog:

Kev Tsim Cov Heterocyclic Scaffolds: 2,5-Hexanedione yog siv rau hauv Paal-Knorr synthesis los tsim cov furans thiab pyrroles hloov. Cov tsib-membered heterocyclic rings no yog cov qauv tshwj xeeb hauv kev kho mob tshuaj, tsim cov hauv paus ntawm ntau yam tshuaj nrog ntau yam kev ua ub no (piv txwv li, antimicrobial, anti-inflammatory, kinase inhibitory).

Kev Tsim Khoom ntawm Pyrrole Derivatives: Los ntawm kev sib xyaw nrog cov amines thawj zaug, 2,5-Hexanedione ua tau zoo tsim tau 2,5-dimethylpyrrole thiab nws cov derivatives. Cov pyrroles no yog lawv tus kheej tseem ceeb intermediates rau kev ua haujlwm ntxiv rau hauv cov molecules nyuaj dua siv hauv kev tshawb fawb thiab kev txhim kho tshuaj.

Ua Ntej rau Cyclic Compounds: Cov tshuaj no tuaj yeem dhau los ua cov tshuaj intramolecular los tsim cov cyclohexenone derivatives, uas yog cov khoom siv tseem ceeb rau kev tsim cov steroidal frameworks thiab lwm yam tshuaj cyclic systems.

Cov Tshuaj Nruab Nrab rau Cov Tshuaj Tshwj Xeeb: Nws ua haujlwm ua cov khoom siv pib hauv kev tsim cov tshuaj nruab nrab siab dua uas tau koom ua ke rau hauv cov tshuaj kawg uas tsom mus rau ntau qhov chaw kho mob, suav nrog cov kab mob hauv lub paj hlwb (CNS) thiab cov kab mob sib kis.

Vim nws lub luag haujlwm hauv cov txheej txheem tsim khoom tseem ceeb no, 2,5-Hexanedione tau teev tseg rau hauv cov txheej txheem tsim khoom rau ntau cov APIs dav dav thiab cov tshuaj tshiab tshawb nrhiav. Peb qib purity siab (> 99%) ua kom muaj kev sib xws, cov qauv tsis muaj kuab paug tsawg, thiab ua raws li cov qauv zoo nruj uas xav tau rau kev tsim tshuaj GMP, txhawb nqa kev txhim kho txhim khu kev qha los ntawm kev tshawb fawb mus rau kev tsim khoom lag luam.
