Аннотация: New derivatives of fused fluoroquinolones bearing five aromatic rings have been obtained. The 19F NMR spectra of these pentacyclic fluoroquinolones demonstrate unusual through space 1H–19F and 19F–19F spin–spin interactions with coupling constants 6J(F, H)=2.0–3.0 Hz, 7J(F, F)=3.5–4.0 Hz and 9J(F, H)=3.0–3.5 Hz. Relative reactivities of fluorine atoms in pentacyclic fluoroquinolones in the amino-defluorination reactions are also different relative to bi- and tricyclic fluoroquinolones????

Аннотация: A rapid development of the resistance of drugs and their toxic and adverse reactions suggest that new antituberculous drugs should be designed. Of the greatest importance is isoniazid resistance. Testing new compounds (IIa, b) has established that the minimum inhibitory concentration of the drug (IIa), 0.39 microgram/ml suppresses the growth of Mycobacterium tuberculosis (MBT) in the macrophages up to 50%, that of the drug (IIb), 1.56 micrograms/ml, causes death in 25% of cases, which is indicative of the high activity of compounds (IIa, b) against MBT
