3. Binciken Gwaji: Haɓakawa da Aiwatar da Kayan Aikin Kayan Aikin Gaggawa
A cikin magani na asali da haɓakar magunguna, abubuwan peptide suna aiki azaman ingantattun ƙwayoyin kayan aiki don haɓaka ingantaccen bincike da ƙirar ƙira.
Binciken hanyoyin sigina
Wasu peptides (misali, Src kinase inhibitory peptides) musamman toshe ayyukan Src iyali kinases, amfani da su don nazarin hanyoyin watsa sigina a cikin yaduwar kwayar halitta da ƙaura. Babban kusancin su yana ba da damar daidaitaccen tsari na takamaiman hanyoyi.
G protein-coupled receptor (GPCR) ligand peptides (misali, PT141 analogs)
Ana amfani da waɗannan peptides don rarraba hanyoyin sadarwar siginar siginar salula mai tsaka-tsaki na GPCR, suna ba da samfura don tantance maƙasudin miyagun ƙwayoyi a cikin cututtukan rayuwa.
Kammalawa
Aiwatar da abubuwan peptide a cikin wasu aikace-aikace na musamman yana ba da haske ga daidaitawa da haɓakar waɗannan ƙwayoyin cuta a cikin al'amuran giciye. A cikin tsarin numfashi, suna ba da kariya daga ƙarshen-zuwa-ƙarshe daga gyaran ƙwayar mucosal zuwa tsoma baki na fibrosis; a cikin ilimin zuciya, suna karya ta hanyar ƙullun magungunan gargajiya ta hanyar angiogenesis da kariyar myocardial; a cikin bincike na gwaji, suna aiki azaman kayan aiki na daidaici don ci gaba da bincike na inji da gano magunguna. Waɗannan aikace-aikacen ba kawai suna cike giɓin jiyya don takamaiman cututtuka ba amma kuma suna nuna haɗin gwiwar abubuwan peptide a cikin bincike na asali da fassarar asibiti.
