Different photoremovable protecting groups in the o-nitrobenzyl, phenacyl, and 2-(o-nitrophenyl)propyl series with a donor-acceptor biphenyl backbone, known to display excellent two-photon absorption cross-sections, were investigated in order to develop efficient two-photon sensitive photoremovable protecting groups. The 2-(o-nitrophenyl)propyl series was a more versatile platform to increase the two-photon sensitivity of photoremovable protecting groups, leading to the p-alkoxy and p-bisalkylamino-4-nitro-[1,1′- biphenyl]-3-yl)propyl derivatives: PENB and EANBP respectively. Those two photoremovable protecting groups are to date the best caging groups for two-photon excitation at 800 and 740 nm respectively, offering attracting perspectives in chemical biology.

Malignant tumor is a disease with high mortality. Traditional treatment methods have many disadvantages, such as side-effects, drug resistance. Because cyclin-dependent kinase 1 (CDK1) plays an indispensable role in cell cycle regulation, it became an att

Herein, we investigated the supramolecular assembly of a modified Yamaguchi reagent TCB-OBt. Interestingly, each molecule is interconnected through novel chalcogen-chalcogen (O?O) interaction, π-π stacking, and aromatic C-H?O interaction. Hirshfeld surface analysis confirmed the existence of uncommon O?O interactions. A well-organized supramolecular layer structure and helical arrangement were observed in the crystal structure. TCB-OBt crystallized in the O-substituted desmotropic form. DFT calculations suggest that the O-substituted form is more stable than theN-substituted form (TCB-(N)-OBt). Morphology analysis indicates the formation of a fantastically well organized, continuous block-shaped system. Furthermore, the designed reagent works as an efficient activating reagent for amide bond formation with good yields under mild reaction conditions. Use of this reagent avoided intractable acid chlorides, and this new mixed-anhydride-based reagent may further be applicable for many other organic transformations.

From the perspective of synthesis, ynones are compounds of considerable interest because of their occurrence in a wide variety of biologically active molecules and as key synthetic intermediates. In this context, a facile and highly efficient synthesis of ynones was developed based on the high reactivity of benzotriazole esters formed in situ. Lithium acetylides can alkylate various carboxylic acids in yields ranging from 60% to 92%. To determine whether our methodology is useful for synthesising complex and biologically relevant molecules, we synthesise d-erythro-sphingosine in four steps and with 33% overall yield from l-serine.

Discovery of 1H-benzo[d][1,2,3]triazol-1-yl 3,4,5-trimethoxybenzoate as a potential antiproliferative agent by inhibiting histone deacetylase

experimental part, p. 8457 - 8462 (2011/02/26)
Twenty-one benzotriazoles (3-16 and 18-24) were synthesized and half of them (5, 8-16, 20, and 21) were reported for the first time. Their antiproliferative activities against three human cancer cells were assayed. It revealed that 1H-benzo[d][1,2,3]triazol-1-yl 3,4,5-trimethoxybenzoate (9) showed considerable activity against three human cancer cell lines with the half maximal inhibitory concentration (IC50) values of 1.2-2.4 nM, which were close to the value of the positive control, doxorubicin. Further investigation indicated compound 9 was a potential histone deacetylase inhibitor (IC50 = 9.4 μM) and its binding mode was simulated using docking method.
