In vitro antiplasmodial, antiamoebic, and cytotoxic activities of some monomeric isoquinoline alkaloids

Twenty-one alkaloids have been assessed for activities against Plasmodium falciparum (multidrug-resistant strain K1) in vitro; 18 of these are reported for the first time. Two protoberberine alkaloids, dehydrodiscretine and berberine, were found to have antiplasmodial IC50 values less than 1 muM, while seven alkaloids – allocrytopine, columbamine, dehydroocoteine, jatrorrhizine, norcorydine, thalifendine, and ushinsunine – had values between 1 and 10 muM. These results are discussed in the context of structure-activity relationships. Compounds were also assessed for antiamoebic and cytotoxic activities, but none was significantly active except for berberine, which was moderately cytotoxic.

Electrophysiological effects of protopine in cardiac myocytes: Inhibition of multiple cation channel currents

1. Protopine (Pro) from Corydalis tubers has been shown to have multiple actions on cardiovascular system, including anti-arrhythmic, anti-hypertensive and negative inotropic effects. Although it was thought that Pro exerts its actions through blocking Ca2+ currents, the electrophysiological profile of Pro is unclear. The aim of this study is to elucidate the ionic mechanisms of Pro effects in the heart. 2. In single isolated ventricular myocytes from guinea-pig, extracellular application of Pro markedly and reversibly abbreviates action potential duration, and decreases the rate of upstroke (dV/dt)(max), amplitude and overshoot of action potential in a dose-dependent manner. Additionally, it produces a slight, but significant hyperpolarization of the resting membrane potential. 3. Pro at 25, 50 and 100 muM reduces L-type Ca2+ current (I(Ca,L)) amplitude to 89.1, 61.9 and 45.8% of control, respectively, and significantly slows the decay kinetics of I(Ca,L) at higher concentration. The steady state inactivation of I(Ca,L) is shifted negatively by 5.9-7.0 mV (at 50-100 muM Pro), whereas the voltage-dependent activation of I(Ca,L) remains unchanged. In contrast, Pro at 100 muM has no evident effects on T-type Ca2+ current (I(Ca,T)). 4. In the presence of Pro, both the inward rectifier (I(K1)) and delayed rectifier (I(K)) potassium currents are variably inhibited, depending on Pro concentrations. 5. Sodium current (I(Na)), recorded in low [Na+](o) (40 mM) solution, is more potently suppressed by Pro. At 25 muM, Pro significantly attenuated I(Na) at most of the test voltages (-60 ~ + 40 mV, with a 53% reduction at -30 mV. 6. Thus, Pro is not a selective Ca2+ channel antagonist. Rather, it acts as a promiscuous inhibitor of cation channel currents including I(Ca,L), I(K), I(K1) as well as I(Na). These findings may provide some mechanistic explanations for the therapeutic actions of Pro in the heart.

Synthesis of indoles via 6pi-electrocyclic ring closures of trienecarbamates

A new method for the preparation of indoles from readily available alpha-haloenones and alpha-(trialkylstannyl)enecarbamates is described. Following a Stille coupling, trienecarbamate 2 is electronically activated to undergo a facile 6pi-electrocyclic ring closure and subsequent oxidation to afford protected aniline 4. Upon deprotection and reductive amination, acid 5 underwent clean cyclization to N-acetylindole 6 (Ac2O, NEt3, 130 C). This method has been used to construct a variety of substituted indoles that are not easily prepared by conventional indole annelation methods. Copyright

Dual C-H functionalization of N-aryl amines: Synthesis of polycyclic amines via an oxidative povarov approach

Iminium ions generated in situ via copper(I) bromide catalyzed oxidation of N-aryl amines readily undergo [4 + 2] cycloadditions with a range of dienophiles. This method involves the functionalization of both a C(sp 3)-H and a C(sp2)-H bond and enables the rapid construction of polycyclic amines under relatively mild conditions.
