Figure 27. Comparison of the L-Clu-induced integrated channel currents between two different preparations of GluR-incorporated BLMs upon injecting the identical concentration of l-GIu (0.10 nM). Applied potential +50 mV. Conditions 9.8 mM HEPES-NaOH (pH 7.6) containing 0.52 M NaCI, 0.19 mM CaCl2, 4.8 mM glycine, 24 pg mL of concanavalin A, 8.1 mM sucrose and 0.40 M formamide in both cis and trans side solutions. Proteoliposomes were injected only to the cis side and agonist solution was added to the trans side. Applied potential +50 mV. The l-GIu solution was injected to the trans side. ...

Halomycins. The halomycins are a group of four antibiotics produced by M.icromonospora halophjtica and separated by partition chromatography on Chromosorb W coated with formamide (19). Further purification was accompHshed using preparative dc (212).

The product can be recrystallized readily from dimethyl-formamide to give yellow leaflets, m.p. 290-293°. However, it is pure enough to be used in the next step. This synthesis has also been applied to the preparation of l,4-bis-[4-( -tolyl)buta-dienyljbenzene (100%), l,4-bis-[4-(3-nitrophenyl)butadienyl]-benzene (56%), and l,4-bis-(3-methyl-4-phenylbutadienyl)ben-zene (87%).

The first attempt to obtain the potential of zero charge of pc-Pb with a mechanically polished and remelted surface was made by Borissova et al.220,221 in 1948 and 1950. Pc-Pb anodically polished in H20 + NaF (0.001 < cNlF < 0.1 M) was studied by Rybalka and Leikis.599 The value of = -0.810 0.02 V(SCE) was found to be independent of c the...

The Leuckart-Wallach reaction is the oldest method of reductive amination of carbonyl compounds. It makes use of formamide, formic acid or ammonium formate at high temperature. The final product is a formamide derivative, which can be converted to an amine by reduction or hydrolysis. The method has been applied to the preparation of 1,2-diamines with a norbornane framework, which are interesting rigid analogues of 1,2-diaminocyclohexanes. As a matter of fact, starting from N-acetyl-2-oxo-l-norbornylamine 222, the diamide 223 was obtained with excellent diastereoselectivity and then converted to the M-methyl-N -ethyl derivative 224 by reduction with borane [ 104] (Scheme 34). On the other hand, when the reac-...
