Does aromaticity in a reaction product increase or decrease the intrinsic barrier? Kinetics of the reversible deprotonation of benzofuran-3(2H)-one and benzothiophene-3(2H)-one

A kinetic study of the reversible deprotonation of benzofuran-3(2H)-one (3H-O) and benzothiophene-3(2H)-one (3H-S) by amines and hydroxide ion in water at 25 C is reported. The respective conjugate bases, 3–O and 3–S, represent benzofuran and benzothiophene derivatives, respectively, and thus are aromatic. The main question addressed in this paper is whether this aromaticity has the effect of enhancing or lowering intrinsic barriers to proton transfer. These intrinsic barriers were either determined from Bronsted plots for the reactions with amines or calculated on the basis of the Marcus equation for the reaction with OH-; they were found to be lower for the more highly aromatic benzothiophene derivative, indicating that aromaticity lowers the intrinsic barrier. It is shown that the reduction in the intrinsic barrier is not an artifact of other factors such as inductive, steric, resonance, polarizability, and pi-donor effects, although these factors affect the intrinsic barriers in a major way. Our results imply that aromatic stabilization of the transition state is ahead of proton transfer; this contrasts with simple resonance effects, which typically lag behind proton transfer at the transition state, thereby increasing intrinsic barriers.

Towards the development of an in vivo chemical probe for cyclin G associated kinase (GAK)

SGC-GAK-1 (1) is a potent, selective, cell-active chemical probe for cyclin G-associated kinase (GAK). However, 1 was rapidly metabolized in mouse liver microsomes by cytochrome P450-mediated oxidation, displaying rapid clearance in liver microsomes and in mice, which limited its utility in in vivo studies. Chemical modifications of 1 that improved metabolic stability, generally resulted in decreased GAK potency. The best analog in terms of GAK activity in cells was 6-bromo-N-(1H-indazol-6-yl)quinolin-4-amine (35) (IC50 = 1.4 muM), showing improved stability in liver microsomes while still maintaining a narrow spectrum activity across the kinome. As an alternative to scaold modifications we also explored the use of the broad-spectrum cytochrome P450 inhibitor 1-aminobenzotriazole (ABT) to decrease intrinsic clearance of aminoquinoline GAK inhibitors. Taken together, these approaches point towards the development of an in vivo chemical probe for the dark kinase GAK.

Addition Reactions of Benzothiophen. Part 4. Reactions of Some Acetoxy- and Hydroxy-benzothiophens with Benzene or Toluene

Heating acetoxybenzothiophens with AlCl3-benzene can give the normal Fries-rearranged products (for the 4-OAc and 7-OAc isomers); these sometimes react further to give their 2,3-dihydro- (for 4-OAc and 7-OAc) or 2-phenyl derivatives (for 6-OAc).Alternatively, benzene can add across the 2,3-double bond of the acetoxy-compound, to give the 2- (for 6-OAc) or 3-phenyl-2,3-dihydrobenzothiophens (for 7-Oac).With AlCl3 in dichloromethane, 6-acetoxybenzothiophen undergoes intermolecular transfer of an acetyl group to give a mixture of 6-acetoxy-2- and 3-acetylbenzothiophens and 6-hydroxybenzothiophen.With AlCl3 in benzene at room temperature, 4-acetoxybenzothiophen gives a rearranged product, 4,5-dihydro-2,4-diphenylbenzothiophen-7(6H)-one (3a) (17percent).In the presence of AlCl3 for 0.5 h, 4-, 5-, 6-, and 7-hydroxybenzothiophens undergo addition of benzene or toluene, to give the appropriate 2-aryl-2,3-dihydrohydroxybenzothiophens (1).Yields are high for the 4- and 6-hydroxy-isomers (80-85percent), but lower for the 5- (55percent) and 7-isomers (10percent).In each of these reactions the starting hydroxybenzothiophen is partly converted into its 2,3-dihydro-derivative. 5- and 7-Hydroxybenzothiophen also each give the same 4,5-dihydro-2,4-diarylbenzothiophen-7(6H)-one (3) (25percent) in this reaction.When the reaction period with benzene or toluene is extended to 5 days, the amount of solvent addition product (1) decreases, but all four hydroxy-isomers now give the same rearranged product (3).The mechanism of this unusual rearrangement is discussed in terms of a spiro-intermediate.

Benzo[b]thiophene-2-carboxamide derivatives as potent urotensin-II receptor antagonists

Members of a series of benzo[b]thiophene-2-carboxamide derivatives, possessing an N-(1-(3-bromo-4-(piperidin-4-yloxy)benzyl)piperidin-4-yl) group, were synthesized and evaluated as urotensin-II receptor antagonists. The results show that these substances have potent UT binding affinities. Observations made in a systematic SAR investigation of the effects of a variety of substituents (R1and R2) at the 5- and 6-positions in the benzo[b]thiophene-2-carboxamide moiety on UT binding affinities led to identification of the 5-cyano analog 7f as a highly potent UT antagonist with an IC50value of 25 nM. Despite having a good metabolic stability, 7f is a potent inhibitor of CYP isozyme and displays an unsuitable PK profile.
