상태 후 CO와 만나서 $({eta}^5-MeCp)Mn(CO)_3와;({eta}^1-allyl)Mn(CO)_5$로 이어지는 것 같다. 그러나 양이온이 $Na^+$인 경우, 이 양이온은 이 반응에서 동종이핵착물의 $Mn(CO)_5$ 부분에서 CO하나를 $({eta}^5-MeCp)Mn(CO)_2$쪽으로 이동시켜 결국 $({eta}^5-MeCp)Mn(CO)_3$로 만들거나 혹은 양이온($Na^+$)과 이탈기인 Cl을 끌어당겨서 반응을 가속화 시키는 역할을 하는 것으로 생각되었다. 이 반응은 각각의 반응물질에 관해서 1차, 따라서 전체적으로 2차 반응이며 이 반응에 관련된 활성화 에너지 관련 매개변수들은 다음과... -

that the other form(s) of cytochroms P450 inducible by pyridine, but not suppressible by YH439 treatment, may play a role in potentiating CCl4-induced hepatotoxicity. YH439 was capable of blocking cadmium chloride-induced liver toxicity in mice. These results demonstrated that YH439 efficiently blocks Vit-A-enhanced hepatotoxiciy through Kupffer cell inactivation and that the suppression of P450 2E1 expression by YH439 is highly associated with blocking of propyl sulfide-mediated hepatotoxicity. -

The aim of this study was to identify volatile and agar-diffusible antifungal metabolites produced by Bacillus sp. G341 with strong antifungal activity against various phytopathogenic fungi. Strain G341 isolated from four-year-old roots of Korean ginseng with rot symptoms was identified as Bacillus velezensis based on 16S rDNA and gyrA sequences. Strain G341 inhibited mycelial growth of all phytopathogenic fungi tested. In vivo experiment results revealed that n-butanol extract of fermentation... -

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist... -

Phosphoryl chloride와 allyl alcohol, 2,3-dibromopropanol, 2-pyrrolidone, ethylenimine을 반응하여 여러가지 phosphate와 phospshoric amide를 합성하였다. 합성한 화합물은 모두 열에 불안정하였으며, allyl phosphorodichloridate와 diallyl phosphorochloridate는 증류하면 상당량의 중합체가 생겼다. IR 스펙트라에서는 $1,300∼1,200 cm^{-1}$에서 P=O stretching의 특성밴드가 나타났으며 NMR 스펙트라는 인원자의 long range coupling 효과로 인해 복잡한 피이크를 보였다. 2,3-dibromopropyl phosphordichloridate의 mass... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2008, Vol.12 No.1 3 13-24 (12 pages)
The aim of the present study was designed to establish comparatively the inhibitory effects of D1-like and D2-like dopaminergic receptor agonists, SKF81297 and R(-)-TNPA on the release of catecholamines (CA) evoked by cholinergic stimulation and membrane depolarization from the isolated perfused model of the rat adrenal medulla. SKF81297 (30ՌM) and R-(-)-TNPA (30ՌM) perfused into an adrenal vein for 60 min, produced great inhibition in the CA secretory responses evoked by ACh... -
