  Anti-Plasmodium activity of tetrazolium salts

  摘要：

  We have previously reported that sulfated cyclodextrins inhibit the invasion of Plasmodium merozoites by interacting with receptors present on the surface of erythrocytes. The observation that tetrazolium salts formed stable complexes with the inhibitory sulfated cyclodextrins suggested that tetrazolium salts might have anti-Plasmodium activity as well. Evaluation of commercially available tetrazolium salts indicated that some were active in the low nanomolar range and showed specificity in their inhibition of Plasmodium. Synthesis of a further 54 structures allowed us to determine that activity results from an aromatic component attached to the tetrazolium carbon atom (R-1) and its size is not critical to the activity of the compound. Nitro modi. cations of active compounds are poorly tolerated, however, the presence of halogen atoms on aromatic groups attached to the nitrogen atoms of the tetrazolium ring (R-2 and R-3) has little effect on activity. Methoxy groups are tolerated on R-2 and R-3 components; however, they are disruptive on the R-1 component. The overall results suggest that the R-1 component is interacting with a specific hydrophobic environment and the R-2 and R-3 components are less constrained. The activity of these compounds in several human and mouse Plasmodium cultures suggests that the compounds interact with a component of the parasite that is both essential and conserved.

  Several 1,3,5-triarylformazans were synthesized (42-77%) using a new methodology. Azo-coupling of aryldiazonium salts with arylaldehyde arylhydrazones under mild basic conditions in two-phase liquid-liquid media is efficiently promoted by phase-transfer catalysts (onium salts or dicyclohexano-18-crown-6) at 5-25°C. The condensation of benzaldehyde with phenylhydrazine followed by phase-transfer catalyzed azo-coupling with phenyldiazonium chloride (one-pot procedure) gave 1,3,5-triphenylformazan in a 54% yield without isolation of the intermediate benzaldehyde phenylhydrazone. A double azo-coupling reaction of phenyldiazonium chloride with 9 different CH-active compounds afforded corresponding formazan only in the case of phenylpyruvic acid. Reaction in malonamide gave 3-carbamoyl-1,5-diphenylformazan instead of the expected 1,5-diphenylformazan.

  采用一种新方法合成了多种 1,3,5-三芳基甲臢（42-77%）。相转移催化剂（鎓盐或二环己烷-18-冠醚-6）可在 5-25°C 的温度下，在两相液液介质的温和碱性条件下有效促进芳基偶氮盐与芳基醛芳基肼的偶氮偶联反应。苯甲醛与苯肼发生缩合反应，然后在相转移催化下与苯基重氮氯化物发生偶氮偶联反应（一锅法），得到 1,3,5-三苯基甲酰肼，收率为 54%，且无需分离中间体苯甲醛苯腙。苯基重氮酰氯与 9 种不同的 CH 活性化合物进行双偶氮偶联反应，只有苯基丙酮酸能得到相应的甲臢。在丙二酰胺中反应得到的是 3-氨基甲酰基-1,5-二苯基甲臢，而不是预期的 1,5-二苯基甲臢。
