A series of analogs of the immunomodulary drugs lenalidomide (1) and pomalidomide (2), in which the amino group is replaced with various isosteres, was prepared and assayed for immunomodulatory activity and activity against cancer cell lines. The 4-methyl and 4-chloro analogs 4 and 15, respectively, displayed potent inhibition of tumor necrosis factor-α (TNF-α) in LPS-stimulated hPBMC, potent stimulation of IL-2 in a human T cell co-stimulation assay, and anti-proliferative activity against the Namalwa lymphoma cell line. Both of these analogs displayed oral bioavailability in rat.

The photolysis of the charge-transfer complex of 1,2,3-trimethylbenzene and tetranitromethane gives a complex mixture of products, most of which arise by initial attack of trinitromethanide ion on the unsubstituted ring positions at C4(C6) and C5 of the radical cation of 1,2,3-trimethylbenzene. The products 7-19 are adducts resulting directly or indirectly from the addition of the elements of tetranitromethane to 1,2,3-trimethylbenzene, and the trinitromethyl aromatic compounds 22-25 are formed by eliminations from intermediate adducts. Six adducts are simple 'single' adducts, nitro-trinitromethyl adducts 7, 8, 10-12, while nitro cycloadduct 9 is formed by cycloaddition of nitro-trinitromethyl adduct 8. The remaining addition products are 'double' adducts, formed by secondary addition reactions initiated by attack of nitrogen dioxide on the buta-1,3-diene system of 'single' adducts, and include trinitro-trinitromethyl compounds 13 and 15, the hydroxy-dinitro-trinitromethyl compound 14, and a group of four nitronic esters 16-19 formed by nitro-denitrocyclization of initially formed hydroxy-trinitromethyl and nitro-trinitromethyl 'single' adducts. Minor amounts of other products are formed including two nitrodienones 21 and 22, and the rearrangement product, 4,5,6-trimethyl-2-nitrophenol (28), and the 2,3,4-trimethyl- and 3,4,5-trimethylnitrobenzenes 26 and 27. The modes of formation of the above products are discussed, and X-ray crystal structure determinations are reported for compounds 9, 13, 14, 18, 19, 22 and 29. Acta Chemica Scandinavica 1996.
Hydrocarbures arylaliphatiques. Partie VIII. Etude cinetique de la protodesilylation de benzocyclenes tricycliques

, p. 498 - 504 (2007/10/02)
A kinetic study of the protodesilylation of silylated derivatives of hemimellitene, 2a,3,4,5 tetrahydro acenaphthene and 1H 2,2a,3,4,5,6 hexahydro benzo(c,d)azulene is described.These results complete those published previously and which are related to the influence of the ring size of alicyclic systems pericondensed to a benzene nucleus on the reactivity of the nucleus to acetylation or bromination.The silylated derivatives were prepared from the corresponding bromo compounds.The synthesis of the bromo compounds, some of which were described in an earlier study, is completed here by using a synthetic pathway which allows the preparation of the β isomers starting from the ortho bromo derivatives.The kinetic results show a deactivation of the β position of the hemimellitene.A little deactivation of ortho α position of the five membered ring in the tricyclic compounds is also observed.This last result, significant in the case of bromination, seems to be related to the Mills-Nixon effect and can be explained by using Streitwieser's hybridization for the ? skeleton.
