Summary: | The aim of the study is to develop the synthesis of a novel series of potent anti-tubercular (anti-TB) activity of 1,3-diphenylpyrazole-based spirooxindolopyrrolizidine derivatives
via
an efficient green approach achieved by using an ionic liquid ([Bmim]BF
4
) under ultrasonication. The title compounds

(X = F/Cl/Br) were produced with high yields in shorter reaction time and well characterized by using spectral techniques; and finally single crystal X-ray diffraction method (

). The newly synthesized compounds were evaluated for their
in vitro
anti-TB activity against
Mycobacterium tuberculosis
H37Rv strain. Among all, six compounds

) exhibited significant anti-TB activity with MIC value 6.25 μg mL
−1
, when compared to the standard drug ethambutol (MIC:1.56 μg mL
−1
).
In silico
molecular docking studies were performed against
M. tuberculosis
enoyl-acyl carrier protein reductase inhibitor. The compounds
4o

4p
,
4y
and
4aa
were exhibited least binding energies −12.58, −12.61, −12.58 and −12.57 kcal mol

, respectively. These results reveal that the produced compounds might be used for the future generation of novel anti-TB drugs.
The study aims to develop and synthesis of a novel series of 1,3-diphenylpyrazole-based spirooxindolopyrrolizidine derivatives as
potent anti-TB agents via
an efficient green approach by using an ionic liquid ([Bmim]BF
4
) under ultrasonication. |
