A new approach to cycloocta[b]indole through formal [5+3] cycloaddition was developed. This methodology was realized by using an indole derivative as a C5 unit and a cyclopropane derivative as a C3 unit. These two units have both donor and acceptor properties. Two carbon-carbon bonds were formed stepwise by the successive addition of a Lewis acidic catalyst and a Bronsted base. The reaction could be performed as a one-pot process. Optically active cycloocta[b]indole was also synthesized by using this methodology with a chiral cyclopropane as a C3 substrate.

Background: ZT55 is a novel natural product isolated from Radix isatidis. It is a highly-selective tyrosine kinase inhibitor against myeloproliferative neoplasms. Although earlier research has described the pharmacodynamic properties of ZT55 in vivo and in vitro, the quantitative determination and pharmacokinetic profile in vivo have not been thoroughly studied. Methods: A novel liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the quantification of ZT55 in rat plasma. A Waters symmetry C18 column was used for chromatographic separation; 0.1% formic acid in acetonitrile and 0.1% formic aqueous solution was used as the mobile phase. Detection was performed by Multiple Reaction Monitoring (MRM) mode using electrospray ionization in the positive ion mode. UPLC-QTOF-MS was used for the identification of metabolites. Results: The method was linear (R-2 =0.9988) over the concentration range of 1-2500 ng/mL. The lower limit of quantification was 1 ng/mL. The intra-day and inter-day precision of ZT55 showed a relative standard deviation within 8.47%, whereas the accuracy (RE) ranged from -4.84% to 4.45%. The recoveries ranged from 92.89% to 97.21%. ZT55 reached the highest plasma concentration at 0.5h. The peak concentrations with three dosages were 103.59 +/- 10.11, 185.23 +/- 29.56, and 355.98 +/- 28.86 ng/mL. The AUC(0-)(24) of three dosages were 874.70 +/- 72.33, 433.80 +/- 49.33, and 231.65++/- 19.41 ng.h/ml respectively. Five metabolites of ZT55 from plasma were confirmed. The main pathways of ZT55 in vivo were hydrolysis, N-dealkylation, glycosylation, and sulfonation. Conclusion: LC-MS/MS method was successfully applied to the pharmacokinetic study of ZT55 after oral administration and intravenous. ZT55 exhibited rapid oral absorption, high elimination, and low absolute bioavailability. This study provides important pharmacokinetic and metabolism information for further pharmacological and toxicological research on ZT55.

Heterologous Expression Guides Identification of the Biosynthetic Gene Cluster of Chuangxinmycin, an Indole Alkaloid Antibiotic

The indole alkaloid antibiotic chuangxinmycin, from Actinobacteria Actinoplanes tsinanensis, containing a unique thiopyrano[4,3,2-cd]indole scaffold, is a potent and selective inhibitor of bacterial tryptophanyl-tRNA synthetase. The chuangxinmycin biosynthetic gene cluster was identified by in silico analysis of the genome sequence, then verified by heterologous expression. Systemic gene inactivation and intermediate identification determined the minimum set of genes for unique thiopyrano[4,3,2-cd]indole formation and the concerted action of a radical S-adenosylmethionine protein plus an unknown protein for addition of the 3-methyl group. These findings set a solid foundation for comprehensively investigating the biosynthesis, optimizing yield, and generating new analogues of chuangxinmycin.

Dehydration stress memory: Insights from physiological responses of sugar apple (Annona squamosa L.) to repeated dehydration stress

Introduction – Evidence from drought hardening as a horticultural practice has demonstrated that exposing plants to repeated dehydration stress alters their physiological responses. Here we investigated the influence of repeated dehydration stress on physiological responses related to dehydration stress memory display in sugar apple. Materials and methods – Sugar apple seedlings were subjected to two successive bouts of dehydration stress with a recovery period in between, while seedlings watered throughout were an untreated control. Results – In the dehydration-stressed seedlings, concentrations of abscisic acid (ABA), indole-3-acetic acid (IAA), jasmonic acid (JA), jasmonoyl-L-isoleucine (JA-Ile), proline and malondialdehyde (MDA) were significantly higher than in the untreated control. On the other hand, the leaf water potential, stomata! conductance, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity were lower in the treated seedlings, although the changes in total chlorophyll were insignificant. Furthermore, the seedlings displayed stress memory as demonstrated by accumulations of IAA and JA-Ile, an increase in MDA concentration, and decreases in total chlorophyll concentration, DPPH free radical scavenging activity, and leaf water potential in the second dehydration stress (S2) compared to the first stress (Si), indicating memory-mediated physiological responses. Meanwhile, ABA, JA, stomatal conductance, and proline concentration exhibited non-memory-mediated responses. Conclusion – These results suggest that accumulations of IAA and JA-Ile during repeated dehydration stress play significant roles as memory-mediated physiological responses for survival in sugar apple.
