  A new quinolinone and its natural/artificial derivatives from a shark gill-derived fungus Penicillium polonicum AP2T1

  摘要：

  Four quinolinones (1-4; 1 is a new compound) were isolated from the static fermentation culture of a shark gill-derived fungus Penicillium polonicum AP2T1. In addition, five new quinolinone derivatives (5-9) and also 1 were obtained in a trimethylsilyldiazomethane-induced methylation reaction of 4. Their structures were elucidated by spectroscopic analyses. In bioassays, compounds 7 and 5 with lactim structures moderately inhibited the proliferation of human cancer cell line HCT116 (wild-type) with IC50-24 h of 8.4 mu g/mL and 30.7 mu g/mL, respectively; the other compounds displayed weaker inhibition. The p53 gene may play some role in their action as suggested by their much weakened activity towards p53-knockout HCT116 cell line. Besides, 6 and 8 exhibited moderate or weak toxicity to brine shrimp larvae, and 3, 4, 8 and 9 showed weak inhibition against Staphylococcus aureus. It is the first report on elucidation of new compounds with origin of shark-derived fungi.

  A novel efficient one-pot regioselective ring-expansion reaction of isatins with in situ generated α-aryl/heteroaryldiazomethanes for the construction of viridicatin alkaloids has been described under metal-free conditions. The utility of this protocol is further demonstrated in the synthesis of naturally occurring viridicatin, viridicatol, and substituted 3-O-methyl viridicatin and their scale up

  α-hydroxyanilide and a diastereoselective aldol cyclization to construct the 3,4-dioxygenated-4-aryl-quinolin-2(1H)-one core. The second approach included a regioselective insertion of aryne into unsymmetric imide to build the N-glycolated 2-amino-benzophenone as a key step. In addition, the dehydrated product of aflaquinolone I, viridicatol (2), was successfully synthesized. We also achieved the chiral resolution

  DOI：10.1021/ol900255g

  日期：2009.4.2

  The efficient synthesis of 3-hydroxy-4-arylquinolin-2(1H)-ones through one-pot Knoevenagel condensation/epoxidation of cyanoacetanilides followed by decyanative epoxide-arene cyclization is described. A convergent assembly with functionalized aldehydes allows for rapid synthesis with diverse substitution patterns. Isolation of 3-hydroxy-4-arylquinolin-2(1H)-ones is readily accomplished by precipitation and filtration.
