Antiproliferative activity of the Antrodia camphorata secondary metabolite 4,7-dimethoxy-5-methylbenzo[d][1,3]dioxole and analogues (Reprinted from Fitoterapia, vol 123, pg 9-12, 2017)

Both the traditional Chinese medicinal fungus, Antrodia camphorata, and its secondary metabolite, 4,7-dimethoxy-5-methylbenzo[d][1,3]dioxole, have been reported to possess promising anticancer activity. In this work the natural product and analogues bearing more polar substituents were synthesised and assessed for antiproliferative activity in the NCI-60 screen. Although each compound inhibited the growth of some cell lines at 10 mu M, none had sufficient activity to warrant further investigation.

A Versatile Total Synthesis of 8-Oxyberberine and Oxohomoberberines

The total syntheses of 8-oxyberberine and oxohomoberberines were accomplished starting from commercially available 5-bromobenzo[d][1,3]dioxole, piperonal and sesamol in high total yield. The key steps involved a modified Pomeranz-Fritsch reaction and the intramolecular Heck cyclization. This approach is short, convenient and suitable for the preparation of homoberberine analogues.

A new approach to alkaloid-like systems: synthesis and crystal structure of 1-(2-acetyl-11-methoxy-5,6-dihydro[1,3]dioxolo[4,5-g]pyrrolo[2,1-a]isoquinolin-1-yl)propan-2-one

The title compound, C19H19NO5, (I), is the product of a domino reaction between cotarnine chloride and acetylacetylene catalysed by copper(I) iodide. The molecule of (I) comprises a fused tetracyclic system containing two terminal five-membered rings (pyrrole and 1,3-dioxole) and two central six-membered rings (dihydropyridine and benzene). The five-membered 1,3-dioxole ring has an envelope conformation and the central six-membered dihydropyridine ring adopts a twist-boat conformation. The acyl substituent is almost coplanar with the pyrrole ring, whereas the methoxy substituent is twisted by 27.93 (16)degrees relative to the benzene ring. The 2-oxopropan-1-yl substituent is roughly perpendicular to the pyrrole ring. In the crystal, molecules are stacked along the a-axis direction; the stacks are linked by weak C-H center dot center dot center dot O hydrogen bonds into puckered layers lying parallel to (001).

Chemical modification of Hyflon (R) AD copolymer end groups by means of physical and chemical treatments. A joint spectroscopic and quantum chemical investigation

In this paper is presented a study on the effects of physical treatments, namely electron beam irradiation or fluorination, on a perfluoropolymer copolymer of tetrafluoroethylene with 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (Hyflon (R) AD copolymer). The analysis has been carried out by means of IR spectroscopy and quantum chemical modeling based on density functional theory; this combined experimental/ theoretical approach has proven effective for the interpretation of previously unassigned IR bands, which are associated to functional groups generated by polymer degradation and chain scission. We performed a systematic screening of chemical groups and structures compatible with degradation pathways that are possible from the chemical point of view: the chemical mechanisms and the correlation with the spectroscopic experimental data (both frequency and intensity) provide guidelines in understanding the phenomena. Moreover, the spectroscopic experimental/theoretical and chemical approaches allowed us to identify some chemical structures responsible for the unassigned IR bands in the C=O stretching frequency region above 1800 cm(-1), which is typical for carbonyl groups in fluorinated systems.

On the non-planarity of 1,3-dioxole and 1,3-dioxolane

The conformational preferences of 1,3-dioxole and 1,3-dioxolane are explained on the basis of the QTAIM electron density analysis of B3LYP/6-311++ G(2d, 2p) electron distributions, supporting the interpretation of the anomeric effect previously proposed by Vila and Mosquera [14]. Thus, distances from methylenic hydrogens to oxygen lone pairs and H-C-O-lp dihedral angles sufficiently explain the atomic population and energy variations, thereby explaining the ring puckering preference.

Crystal chirality was assigned to correspond to the known chirality of the precursor compound. The cyclopentane ring exhibits an envelope conformation (E1) where C(1) occupies the flap position [0.58 angstrom from the plane of C(2), C(3), C(5) and C(6)]. The dioxole ring is in an unusual planar conformation. This planarity may be partially attributed to the disorder of the C-(CH3)2 moiety at the C(4) position. The cyclohexyl ring exhibits a chair conformation (4C1) where atoms C(8) and C(11) are 0.61 angstrom and -0.66 angstrom, respectively, from the plane of atoms C(9), C(10), C(12) and C(13).

Selective, competitive and mechanism-based inhibitors of human cytochrome P450 2J2

Twenty five derivatives of the drugs terfenadine and ebastine have been designed, synthesized and evaluated as inhibitors of recombinant human CYP2J2. Compound 14, which has an imidazole substituent, is a good non-competitive inhibitor of CYP2.12 (IC50 – 400 nM). It is not selective towards CYP2.12 as it also efficiently inhibits the other main vascular CYPs, such as CYP2B6, 2C8. 2C9 and 3A4: however, it could be an interesting tool to inhibit all these vascular CYPs. Compounds 4, 5 and 13, which have a propyl, allyl and benzo-1,3-dioxole terminal group, respectively, are selective CYP2J2 inhibitors. Compound 4 is a high-affinity, competitive inhibitor and alternative substrate of CYP2J2 (K-i = 160 50 nM). Compounds 5 and 13 are efficient mechanism-based inhibitors of CYP2J2 (k(inact)/K-i values similar to 3000 L mol(-1) s(-1)). Inactivation of CYP2J2 by 13 is due to the formation of a stable iron-carbene bond which occurs upon CYP2J2-catalyzed oxidation of 13 with a partition ratio of 18 +/- 3. These new selective inhibitors should be interesting tools to study the biological roles of CYP2J2. Published by Elsevier Inc.
