Diaminopyrimidine Oxide yog dab tsi?
Diaminopyrimidine Oxide, feem ntau paub hauv kev lag luam tu plaub hau li Kopexil (CAS 74638-76-9), yog ib qho khoom siv hluavtaws los ntawm tsev neeg pyrimidine. Nws yog dav siv nyob rau hauv cov khoom tu plaub hau raws li ib tug txias thiab tiv thaiv plaub hau poob active ingredient.
Raws li txoj cai, nws qhia qhov zoo sib xws nrog minoxidil - qhov zoo -paub cov plaub hau kev loj hlob tus neeg saib xyuas - thaum raug cais nruj raws li ib tugcov khoom siv tshuaj pleev ib cees tsis yog cov khoom siv tshuaj. Qhov no tso cai rau cov kws tsim tshuaj pleev ib ce los tsim cov tshuaj tiv thaiv zoo -cov plaub hau poob raws li cov qauv kev cai tshuaj pleev ib ce, yam tsis muaj kev pom zoo nruj rau cov tshuaj siv tshuaj.
Cov khoom xyaw no feem ntau muab tso rau hauv ntau yam khoom siv plaub hau, suav nrog tshuaj zawv plaub hau, tshuaj pleev, tshuaj pleev, tshuaj tonics, thiab tshuaj pleev tawv taub hau. Nws ua raws li ob qho tib si cov plaub hau txias thiab tus neeg saib xyuas tawv taub hau, tswj cov tawv taub hau kev noj qab haus huv thaum txhim kho sab hauv ua rau cov plaub hau tsis ntxov ntxov.
Mechanism ntawm Action
Diaminopyrimidine Oxide txhawb cov plaub hau kev loj hlob thiab txo cov plaub hau poob los ntawm ntau txoj hauv kev lom neeg:
- 5 -Reductase Inhibition
Nws inhibits 5 -reductase, enzyme uas hloov testosterone rau hauv dihydrotestosterone (DHT). Tshaj DHT yog ib qho tseem ceeb ntawm cov plaub hau follicle miniaturization hauv androgenetic alopecia. Kev tswj hwm qib DHT hauv zos nyob ib ncig ntawm cov hauv paus hniav, nws pab txhawb kev loj hlob ntawm cov plaub hau.
- Potassium Channel ua kom
Zoo ib yam li minoxidil, cov khoom xyaw no tuaj yeem qhib cov poov tshuaj hauv cov hauv paus plaub hau, txhawb kev vasodilation thiab txhim kho tawv taub hau microcirculation. Cov ntshav ntws zoo dua muab cov pa oxygen ntau dua thiab cov khoom noj ncaj qha rau cov hauv paus plaub hau.
- Anagen Phase Prolongation
Nws txuas mus rau anagen (txoj kev loj hlob) theem ntawm lub voj voog plaub hau thiab ncua kev nkag mus rau telogen so theem, pab tswj cov plaub hau ruaj khov ntev ntev -.
- Perifollicular Collagen Regulation
Ntau dhau ntawm collagen stiffening nyob ib ncig ntawm cov hauv paus plaub hau tuaj yeem ua rau follicle fibrosis thiab nce thinning. Cov khoom xyaw no pab soften perifollicular collagen, tiv thaiv follicle qauv thiab tswj kev ua haujlwm ntawm lub cev.
Cov txiaj ntsig tseem ceeb ntawm Kopexil hauv Kev Kho Plaub Hau
1. Superior Cov plaub hau loj hlob muaj peev xwm vs Minoxidil
Ib tug 2024 cov phooj ywg- tshuaj xyuas tsiaj kev tshawb fawb indexed hauv PubMed piv qhov ua tau zoo ntawm 5% hydro- cov kua dej cawv muaj Diaminopyrimidine Oxide nrog minoxidil tshaj 28 hnub[1].
Cov kev tshawb pom tseem ceeb [1]:
- Pab pawg Diaminopyrimidine Oxide tau pom tias muaj kev txhim kho tseem ceeb hauv cov plaub hau hnyav, suav follicle, anagen plaub hau piv thiab tag nrho cov plaub hau kev loj hlob piv nrog minoxidil pawg.
- Kev nthuav qhia ntau dua ntawm cov plaub hau kev loj hlob- muaj feem cuam tshuam xws li VEGF thiab HGF tau kuaj pom hauv Diaminopyrimidine Oxide pab pawg kho.
- Kev kuaj tshuaj lom tau pom tias tsis muaj qhov sib txawv ntawm qhov hnyav hauv lub cev lossis kev hloov pauv morphological thoob plaws hauv pawg, lees paub qhov zoo biocompatibility thiab kev nyab xeeb.
Txoj kev tshawb no tau lees paub tias 5% cov mis nrog cov khoom xyaw no ua haujlwm zoo li cov plaub hau kev loj hlob, uas qhia tau hais tias tag nrho cov kev ua tau zoo thiab siv tau rau cov tshuaj pleev ib ce los tiv thaiv- daim ntawv thov plaub hau poob.[1].
2. Paj Lugen Real-World Efficacy
Ib qho loj -txoj kev soj ntsuam thoob ntiaj teb tau tso npe rau 527 tus neeg koom nrog me me androgenetic alopecia, siv cov qauv tawv taub hau uas muaj Diaminopyrimidine Oxide, arginine, thiab piroctone olamine[2].
Cov txiaj ntsig tom qab 3 lub hlis ntawm kev siv tas li[2]:
| Metric | Kev tshwm sim |
|---|---|
| Zuag qhia tag nrho cov plaub hau poob | 89.0% |
| Cov plaub hau txo qis (poj niam) | 92.5% |
| Cov plaub hau txo qis (txiv neej) | 83.8% |
| Qhov nruab nrab cov neeg siv tau siab | 7.9 ± 1.7 |
| Zoo / zoo heev rau daim tawv nqaij | 98.6% |
Cov kev tshawb fawb tau tshawb pom tias cov formulations uas muaj cov active ingredient no zoo txhim kho me ntsis androgenetic alopecia rau cov txiv neej thiab cov poj niam, nrog ib tug qab ntxiag kev ntxhib los mos thiab siab siv siab ntev.[2].
3. Cov tawv nqaij zoo Permeation & Formulation Stability
A 2026 cov phooj ywg- tshawb xyuas kev tshawb fawb soj ntsuam cov khoom siv lub cev, kev ruaj khov, thiab daim tawv nqaij permeation peev xwm ntawm Diaminopyrimidine Oxide piv nrog minoxidil[3].
Siv HPLC nrhiav kom tau thiab Franz diffusion cell test, cov ntaub ntawv tau lees tias nws superior transdermal permeation kev ua tau zoo, pab cov khoom xyaw nquag mus txog thaj tsam follicle zoo dua.[3].
Kev ntsuam xyuas kev ruaj ntseg qhia tau tias nws cov qauv ua tiav t90 txee- lub neej ntawm 39-50 lub hlis raws li cov txheej txheem khaws cia, muab sijhawm ntev - kev ruaj ntseg rau cov khoom lag luam tu plaub hau.
4. Kev nyab xeeb siab & Nrhav kev tswj hwm kev ua raws cai
Lub 2023 Cosmetic Ingredient Review (CIR) qhov kev ntsuam xyuas zaum kawg tau faib Diaminopyrimidine Oxide kom nyab xeeb rau kev siv cov plaub hau txias thiab kho tawv taub hau.[4].
Ntiaj teb no txoj cai txwv[4][5]:
- EU: Txwv rau max 1.5% tawm hauv - ntawm cov khoom siv plaub hau
- Tuam Tshoj: Muab cais raws li txwv tsis pub siv tshuaj pleev ib ce, siab tshaj 1.5% hauv cov tshuaj tu plaub hau
- Teb Chaws Asmeskas: Tso cai rau kev siv tshuaj pleev ib ce ntawm qhov tsim nyog, tsis pom zoo ua tshuaj
Cov kev tshawb fawb txog kev nyab xeeb ntawm tsiaj kuj tau lees paub tias tsis muaj kev cuam tshuam hauv nruab nrog cev ntawm qhov siv tau ntau. Piv nrog minoxidil, nws zam cov kev mob tshwm sim xws li ntshav siab hloov pauv, ua rau nws muaj kev nyab xeeb rau lub sijhawm ntev - daim ntawv thov tshuaj pleev ib ce.
