  New Bis-thiazolium Analogues as Potential Antimalarial Agents: Design, Synthesis, and Biological Evaluation

  摘要：

  Bis-thiazolium salts are able to inhibit phosphatidylcholine biosynthesis in Plasmodium and to block parasite proliferation in the low nanomolar range. However, due to their physicochemical properties (i.e., permanent cationic charges, the flexibility, and lipophilic character of the alkyl chain), the oral bioavailability of these compounds is low. New series of bis-thiazolium-based drugs have been designed to overcome this drawback. They feature linker rigidification via the introduction of aromatic rings and/or a decrease in the overall lipophilicity through the introduction of heteroatoms. On the basis of the structure-activity relationships, a few of the promising compounds (9, 10, and 11) were found to exhibit potent antimalarial in vitro and in vivo activities (EC50 < 10 nM and ED50 ip < 0.7 mg/kg).

  A transition metal free, acid promoted cascade hydroalkoxylation–formal [4+2] cycloaddition of various alkynols with salicylaldehyde is demonstrated for the synthesis of tetrahydrofurano/pyrano‐chromenes and spiroketals. In general, alkynols underwent hydroalkoxylations in an endo‐dig manner when internal alkynes were used to furnish the heteroannular ketals, whereas terminal alkynes proceeded in an

  证明了无过渡金属，酸促进的各种炔醇与水杨醛的级联加氢烷氧基化–正式[4 + 2]环加成反应可合成四氢呋喃/吡喃-铬酮和螺酮。一般来说，炔醇经历在hydroalkoxylations内切-挖方式时内部炔烃被用来提供所述heteroannular缩酮，而末端炔烃在进行外切-挖引领潮流的时尚。研究表明，当偶合伙伴是水杨醛时，炔醇的分子内加氢烷氧基化是生成氧鎓离子的首选途径。这种无金属的转化为快速选择性地合成四氢呋喃呋喃和吡喃铬酮提供了新的途径。
