Abstract
LC-MS-oriented fractionation of the sponge Aaptos suberitoides resulted in the isolation of four heptacyclic alkaloids, aaptodines A-D (1-4), which contain 9,10-dihydrofuro[2,3-f][1,3]oxazolo[5,4-h]quinolone and 7,8-dihydrocyclopenta[de][1,6]naphthyridine subunits with a spiro carbon atom. The structures were determined on the basis of NMR spectroscopic and single-crystal X-ray diffraction data analysis aided by electronic circular dichroism calculations and Mosher's method. A biosynthetic pathway for the formation of aaptodines A-D is postulated. Aaptodine D exhibits potent inhibition against osteoclast formation.

Dyshlovoy SA. Blue-Print Autophagy in 2020: A Critical Review. Mar Drugs 2020; 18:md18090482. [PMID: 32967369 PMCID: PMC7551687 DOI: 10.3390/md18090482] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 09/15/2020] [Accepted: 09/17/2020] [Indexed: 12/13/2022] Open
Abstract
Autophagy is an elegant and complex biological process that has recently attracted much attention from the scientific community. The compounds which are capable of control and modulation of this process have a promising potential as therapeutics for a number of pathological conditions, including cancer and neurodegenerative disorders. At the same time, due to the relatively young age of the field, there are still some pitfalls in the autophagy monitoring assays and interpretation of the experimental data. This critical review provides an overview of the marine natural compounds, which have been reported to affect autophagy. The time period from the beginning of 2016 to the middle of 2020 is covered. Additionally, the published data and conclusions based on the experimental results are re-analyzed with regard to the guidelines developed by Klionsky and colleagues (Autophagy. 2016; 12(1): 1–222), which are widely accepted by the autophagy research community. Remarkably and surprisingly, more than half of the compounds reported to be autophagy activators or inhibitors could not ultimately be assigned to either category. The experimental data reported for those substances could indicate both autophagy activation and inhibition, requiring further investigation. Thus, the reviewed molecules were divided into two groups: having validated and non-validated autophagy modulatory effects. This review gives an analysis of the recent updates in the field and raises an important problem of standardization in the experimental design and data interpretation.

Abstract
We have found that 2-methoxy-1,4-naphthoquinones easily react with primary alcohols to produce the corresponding 2-alkoxyderivatives. Using this reaction, we synthesized methyl-6-O-(naphthalene-1,4-dione-2-yl)-α-D-glucopyranosides, a new type of water soluble quinone-carbohydrate nonglucoside conjugates. The resulting conjugates induced apoptosis in human cancer HeLa and normal mouse JB6 P(+) Cl41 cells with simultaneous inhibition of p53-dependant transcriptional activity, suggesting that the observed cell death was p53-independent. Furthermore, we analyzed structure-activity relationship and bioactivity of 2-hydroxy- and 2-methoxy-1,4-naphthoquinones as well as carbohydrate nonglucoside conjugates. All compounds containing a quinone moiety were able to inhibit p53-dependant transcriptional activity and exerted moderate inhibitory effects on HeLa cell colony formation. Investigations of structure-activity relationships revealed that cytotoxicity depended on the type of substituent at C-2 of the quinone moiety, decreasing in the following order: methoxyderivatives > carbohydrate nonglucoside conjugates > hydroxyderivatives. Furthermore, cytotoxicity depended on the position of the hydroxy substituent in the quinone moiety in all derivatives and decreased in the following order: 8- > 5- > 5,8-derivatives. In conclusion, this is the first report on synthesis and biological structure-activity relationships of the new class of quinone-carbohydrate nonglucoside conjugates.

Abstract
Three new aaptamine-type alkaloids, 2,3-dihydro-2,3-dioxoaaptamine (1), 6 -( N-morpholinyl)-4,5-dihydro-5-oxo-demethyl(oxy)aaptamine (2) and 3-(methylamino)demethyl(oxy)aaptamine (3), along with known aaptamines were isolated from the sponge Aaptos sp. Their structures were determined on the basis of detailed analysis of their 1D and 2D NMR spectroscopic and mass spectral data. The isolated compounds induced apoptosis in human leukemia THP-1 cells.
