hoʻomākaukau
Hoʻomākaukau o aminoguanidine hydrochloride: 9 g o aminoguanidine carbonate i hoʻokomo ʻia i loko o kahi 250ml ʻekolu pahu ipu, ua hoʻohui ʻia ka 20ml o ka ethanol paʻa loa, ʻaʻole hiki ke hoʻohana ʻia ka paʻa i ka ethanol anhydrous e hana i kahi hoʻomaha. Ma lalo o ka hoʻonāukiuki ʻana i ka mahana o ka lumi, hoʻohui ʻia ka hui ʻana o 6ml 30% concentrated hydrochloric acid a me 10ml o ka ethanol āpau a hiki i ka loaʻa ʻole o kahi huʻa, a laila hoʻomau ʻia ka hopena hoʻonāukiuki i ka mahana o ka lumi no 1 mau hola. Hoʻomehana ʻia ka hoʻomaha i loaʻa e hoʻopau loa i ka paʻa, a laila hoʻohaʻahaʻa maoli ʻia i ka mahana o ka lumi. Ma hope o ka hoʻoneʻe ʻia i ka pahu hau a hoʻonoho ʻia i ka pō, ke aniani keʻokeʻo keʻokeʻo me ka pae hoʻoheheʻe o 166-167℃ ua loaʻa.

He ʻano like ʻole kā Daidzein o nā hopena lāʻau, ka pale ʻana a me ka mālama ʻana i nā ʻano maʻi like ʻole. Ua hōʻike ʻo Cn200910144204.1 hiki ke hoʻohana ʻia ka aminoguanidine hydrochloride e hoʻomākaukau i kahi daidzein hoʻololi ʻia kemika, ʻo ia hoʻi, daidzein 7,4 '- oxy aminoguanidine acetate. ʻO ka soybean aglycone 7,4 '- oxy aminoguanidine acetate kahi hui prodrug, kahi e hoʻokuʻu i ka lāʻau makua - daidzein ma lalo o nā kūlana physiological, a hoʻomaikaʻi i ka solubility o kona wai e ka paʻa covalent.
ʻO ka hoʻomākaukau ʻana o Daidzein 7,4 ' - o-aminoguanidine acetate: Ua hoʻoheheʻe ʻia ka 0.5g aminoguanidine hydrochloride i ka 100ml acetone, 0,02g phase transfer catalyst, 0.5g anhydrous potassium carbonate, 0.5g 7,4 ' - chloroacetyl daidzein a me 0.02g I2 i hoʻohui ʻia i loko o ka hopena. Lawe ʻia ka hopena ma ke ana wela o ka lumi no 24 mau hola. Ua hoʻopau ʻia ʻo Acetone mai ka kānana ma lalo o ke kaomi hoʻemi ʻia, a laila hoʻokaʻawale ʻia e ke kolamu gel silica. ʻO ka eluent ka ethyl acetate: ʻaila ʻaila ʻaila ke kaulike ʻo 1 : 2, loaʻa ke kōpaʻa paʻa keʻokeʻo.
