From the reaction of potassium bisulphite with D-glucose the glucose-potassium bisulphite addition compound, D-glycero-D-ido-1,2,3,4,5,6-hexahydroxyhexyl potassium sulphonate was prepared pure and crystalline. Similar new compounds were prepared from the reaction of potassium bisulphite with D-galactose, L-rhamnose, D-mannose, and L-arabinose. The reaction of the glucose-potassium bisulphite addition compound with aniline, gave pure crystalline D-glycero-D-ido-1-anilino-2,3,4,5,6-pentahydroxyhexyl potassium sulphonate. Similar derivatives were prepared from p-toluidine, p-anisidine, and o-phenylenediamine. The aniline and p-toluidine derivatives were also prepared from the glucose-sodium bisulphite addition compound.

The crystalline glucose-aniline bisulphite addition compound, D-glycero-D-ido-1-anilino-2,3,4,5,6-pentahydroxyhexyl anilinium sulphonate, was prepared from the reaction of D-glucose with aniline bisulphite in water and in methanol. The D-glycero-D-ido-1-anilino-2,3,4,5,6-pentahydroxyhexyl piperidinium sulphonate was prepared by adding piperidine bisulphite to preformed N-phenyl-D-glucosylamine. Other new compounds of similar structure were prepared from the reaction of aniline bisulphite with D -galactose and D-mannose. cycloHexylamine bisulphite reacted with D-glucose to form crystalline D-glycero-D-ido-1,2,3,4,5,6-hexahydroxyhexyl cyclohexylammonium sulphonate. When treated with aniline this compound formed D-glycero-D-ido-1-anilino-2,3,4,5,6-pentahydroxyhexyl cyclohexylammonium sulphonate. The D-glycero-D-ido-1-anilino-2,3,4,5,6-pentahydroxyhexyl potassium and anilinium sulphonates were interconverted by use of a cation-exchange resin. Acetylation of the anilinium sulphonate in pyridine gave the tetra-acetate of N-phenyl-D-glucosylamine.

Abstract Euphopepluanones F − K (1 − 4), four new jatrophane type diterpenoids were isolated from the seeds of Euphorbia peplus, along with eight known diterpenoids (5 − 12). Their structures were established on the basis of extensive spectroscopic analysis and X-ray crystallographic experiments. The new compounds 1 − 4 were assessed for their activities to induce lysosomal biogenesis through LysoTracker Red staining. Compound 2 significantly induced lysosomal biogenesis. In addition, compound 2 could increase the number of LC3 dots, indicating that it could activate the lysosomal-autophagy pathway. Graphic Abstract

S-substituted perhalo-2-nitrobuta-1,3-dienes 3a, b were synthesized by the reaction of polyhalo-2-nitrobuta-1,3-dienes 1a, b with allyl mercaptan. 1-(2,3-Dibromopropanethio)-4-bromo-1,3,4-trichloro-2-nitrobuta-1,3-diene 4 was obtained from the addition of bromine to S-substituted polyhalo-2-nitrobuta-1,3-diene 3b in carbon tetrachloride. Sulfoxides 5a, b, and 6 were obtained from the reaction of thiosubstituted polyhalonitrobutadienes 3a, b, and 4 with m-CPBA in CHCl3. The structures of the new compounds were determined by spectroscopic data (FTIR, 1H NMR, 13C NMR, MS). These compounds exhibited antixanthine oxidase, antityrosinase, antielastase, and antineuraminidase activities.

Four years after the discovery of superconductivity at high temperature in the Ba-La-Cu-O system, more than thirty new compounds have been synthesized, which can be classified in six series of copper oxides: La2CuO4 - type oxides, bismuth cuprates, YBa2Cu3O7 family, thallium cuprates, lead cuprates and Nd2CuO4 - type oxides. Despite their quite different specific natures, close relationships allow their structures to be simply described through a single mechanism. The fifth first families can indeed be described as intergrowths of multiple oxygen deficient perovskite slabs with multiple rock salt-type slabs, according to the representation [ACuO3-x]m [AO]n.The n and m values are integer in the parent structures, n varying from 0 to 3 and m from 1 to 4; every member of this large family can thus be symbolized by [m,n]. The oxygen deficient character of the perovskite slabs involves the existence or the co-existence of several types of copper environment: octahedral, pyramidal and square planar.Both mechanisms, oxygen deficiency and intergrowth, are well known to give rise easily to nonstoichiometry phenomena. Numerous and various phenomena have actually been characterized in these cuprates, strongly depending on the thermal history of the samples.
