4-Hydroxy-2-quinolones 155*. Bioreversible chemical modification of chinoxycaine at the tertiary amino group as a method of improving its pharmaceutical activity
摘要:
There are discussed several variants of the chemical modification of the local anesthetic chinoxicaine at the tertiary amino group, initially in use as the hydrochloride. It was found that a significant improvement in its pharmaceutical properties can be achieved by exchange of the hydrogen chloride for an alternative salt forming acid component.

2-e]- and [2,3-e]-1,2-thiazine-6-sulfonamide 1,1-dioxides were synthesized for evaluation as potential candidates for the treatment of glaucoma. All of the compounds prepared were potent high affinity inhibitors of human carbonicanhydrase II, Ki < 0.5 nM. Additionally, inhibition of recombinant human carbonicanhydrase IV was determined for selected compounds; these were shown to be moderate to potent

Cucurbit[7]urilhost–guest complexes of cholines and phosphonium cholines in aqueous solution

The neutral host cucurbit[7]uril forms very stable complexes with a series of cationic cholines (R3NCH2CH2ORâ²+) and their phosphonium analogues (R3PCH2CH2ORâ²+) (R3 = Me3, Et3, or Me2Bz, or R3N = quinuclidinium, and Râ² = H, COCH3, CO(CH2)2CH3, or PO3H), and (±)-carnitine, in aqueous solution. The complexation behaviour has been investigated using 1H and 31P NMR spectroscopies, and ESI mass spectrometry. The complexation-induced chemical shift changes of the guests clearly indicate the effects of replacing the N(CH3)3+ end group by P(CH3)3+, and changing the nature of R on the position of the guest with respect to the CB[7] cavity and its polar portal-lining carbonyl groups. This study demonstrates that molecular recognition of cholines in aqueous solution is achievable with a neutral host without the need for aromatic walls for cationâÏ interactions.
