Discovery of Macrocyclic Inhibitors of Apurinic/Apyrimidinic Endonuclease 1

Apurinic/apyrimidinic endonuclease 1 (APE1) is an essential base excision repair enzyme that is upregulated in a number of cancers, contributes to resistance of tumors treated with DNA-alkylating or -oxidizing agents, and has recently been identified as an important therapeutic target. In this work, we identified hot spots for binding of small organic molecules experimentally in high resolution crystal structures of APE1 and computationally through the use of FTMAP analysis (http://ftmap.bu.edu/). Guided by these hot spots, a library of drug-like macrocycles was docked and then screened for inhibition of APE1 endonuclease activity. In an iterative process, hot-spot-guided docking, characterization of inhibition of APE1 endonuclease, and cytotoxicity of cancer cells were used to design next generation macrocycles. To assess target selectivity in cells, selected macrocycles were analyzed for modulation of DNA damage. Taken together, our studies suggest that macrocycles represent a promising class of compounds for inhibition of APE1 in cancer cells.

New insights into the torquoselectivity of the staudinger reaction

To understand the torquoselectivity and the electronic effects of the Staudinger reaction, a study using a combination of experiments and DFT calculations has been conducted for the reactions of an unsymmetric cyclicketene and cyclic imines with different electronic properties. The pred ominant formation of the donor-in beta-lactams, the torquoelectronically disfavored products, was observed for the first time. The Hammett analyses reveal a close relationship between the donor-out/donor-in productratio and the electronic nature of the imines. The kinetic competition experiments and DFT calculations indicate that the two-step Staudinger r eaction shows different rate-determining steps in the donor-in and donor-out pathways. Our investigations reveal that the torquoelectronic control in the Staudinger reaction is quite different from that in the ring-opening reaction of cyclobutene derivatives. The diastereoselectivity of the Staudinger reaction involving an unsymmetric disubstituted ketene cannot be simply rationalized or predicted by the torquoelectronic model.

Intramolecular Cyclization of Some Unsaturated Alcohols by Means of Thallium Triacetate

Reactions of some primary and secondary Delta4-, Delta5- and Delta6-alkenols with thallium triacetate (TTA) in benzene, acetic acid and chloroform as solvent have been investigated.When terminally unsubstituted Delta4-alkenols, such as 4-penten-1-ol (5a) and 5-hexen-2-ol (5b), are treated with TTA in benzene, beta-acetoxylated tetrahydrofurans 8a and 8b are obtained.However, when the reaction is carried in acetic acid the products are both regioisomers, i.e. five- and six-membered cyclic ethers (8a, 8b, 7a and 7b). 4-Methyl-4-penten-1-ol (5c) is converted in benzene into a mixture of products (8c and 7c) in which the tetrahydropyran derivative 7c is predominant, and in acetic acid it is the sole cyclization product.Terminally dialkylated alkenols, such as 5-methyl-4-hexen-1-ol (1b) and 6-methyl-5-hepten-2-ol (1c), are converted into beta-acetoxylated (4b and 4c) and unsaturated cyclic ethers (9a and 9b), in both cases of the tetrahydrofuran type. 5-Hexen-1-ol (10) and 6-hepten-1-ol (11) cyclize to the corresponding six- (13) and seven-membered cyclic ether (14), respectively.Organothallium intermediates have been isolated and identified in the cases of alcohols 5a, 5c and 10, proving that the TTA addition to the double bond has originally obeyed the Markovnikov rule.

High resolution rotational spectroscopy and ring-puckering conformation of 3-hydroxytetrahydrothiophene

High resolution rotational spectra have been recorded for 3-hydroxytetrahydrothiophene and its 34S and 13C isotopomers using a Fourier-transform microwave spectrometer. The spectroscopic moments of inertia were used to least-squares fit the ring puckering conformation. The structure was found to have C(3) puckered out of plane, and it is stabilized by a 2.634-A hydrogen bond from the hydroxyl group to the thioether. Ab initio calculations, at the MP2/6-31G** level, also found that the C(3) puckered conformation is the lowest energy conformation of the ring. Measurements of the Stark shifts were used to determine the dipole moment (mu = 1.556 (4) D) of 3-hydroxytetrahydrothiophene and its projections onto the principal inertial axes (mua = 0.024 (5) D, mub = 0.944 (5) D, and muc = 1.237 (4) D).
