Anti-promastigote activity. L. donovani promastigote inhibition potency of these reported β-carboline derivatives was determined by Alamar blue assay method. Among these analogues, compound 7d exhibited potent inhibition (EC50 0.91 µM) of L. donovani promastigotes than standard drugs pentamidine and miltefosine (EC50 6.4 and 3.12 µM). Anti-promastigote activity of analogues 7h, 7n and 7g (EC50 4.0, 4.57, and 5.02 µM respectively) is equipotent as that of standard drugs. Compounds 7f, 7p, 7c, 7a, 7k, 7j, 7b, 7i, and 7odisplayedsignificant inhibition (EC50 8.42, 8.5, 9.45, 11.9, 12.4, 13.1, 14.2, 15.2 and 19.5 µM respectively) of promastigote and inhibition potency is comparable with standard drugs. Compound 7e showed moderate (EC50 28.5 µM) anti-promastigote activity and 7l and 7m displayed weak inhibition (EC50 85.9 and 117.5 µM) of L. donovani promastigotes.

 

Axenic amastigote screening.

Compounds exhibited significant anti-promastigote activity (EC50 < 20 µM), were further screened against axenic amastigote (human life cycle parasite form) forms. Among these derivatives, Analogues 7d, 7h, 7n and 7g showed potent inhibition (EC50 0.9, 2.2 3.5 and 3.8 µM respectively) of axenic amastigotes. Especially, compound 7d exhibited two to three times more potent anti-amastigote activity than pentamidine and miltefosine (EC50 1.6 and 2.8 µM). Compounds 7c, 7b, 7f, 7j, 7k and 7a exhibited significant inhibition (EC50 5.3, 5.8, 6.4, 7.5, 9.3 and 10.0 µM respectively) of L. donovani axenic amastigotes. Compounds 7p, 7o and 7i displayed moderate anti-amastigote activity (EC50 12.3, 13.9 and 19.4 µM respectively). Axenic amastigote assay results revealed that these β-carboline derivatives exhibited potent inhibition of axenic amastigotes of L. donovani.

 

Intracellular amastigote screening.

Although, axenic amastigotes assay most commonly used to screen new leishmanial agents are different from intracellular amastigotes in terms of protein expression and drug susceptibility. Hence in our present study, compounds displayed potent inhibition of promastigote and axenic amastigotes were further evaluated against intracellular amastigotes to ensure their activity against clinical relevant forms of parasite.

 

Intracellular amastigote assay results suggested that, most of these analogues displayed potent inhibition of L. donovanimacrophagic amastigotesand the potency was comparable with miltefosine and many folds higher than pentamidine (Table 2). Especially, compound 7d ((4-(4-methoxyphenyl)piperazin-1-yl)(9-methyl-1-phenyl-9H-pyrido [3,4-b]indol-3-yl)methan-one) exhibited five times potent inhibition (EC50 1.3 µM) of intracellular amastigotes compared to miltefosine (EC50 6.4 µM). Compounds 7n and 7g were displayed potent antiamastigote activity (EC50 5.6 and 6.3 µM) than standard drugs
miltefosine and pentamidine with better selectivity index. Antiamastigote potency of 7b, 7c, 7h, 7o and 7p (EC50 7.2, 7.8, 7.9, 7.9 and 9.4 µM) is comparable with miltefosine and better than pentamidine. Compounds 7k, 7f, 7a, 7j and 7i exhibited good antiamastigote activity (EC50 10.1, 11.8, 13.5, 15.4 and 22.0 µM) with better selectivity.

 

Structure Activity Relationship (SAR).

Structure activity relationship study suggests that, substitution or replacement of phenyl ring has significant effect on anti-leishmanial activity as well as cytotoxicity of these analogues. Among these analogues, un-substituted phenyl derivative displayed significant inhibition of promastigotes, axenic amastigote and intracellular amastigotes of L. donovani. Ortho-para directing methyl group substitution on ortho and para position enhanced the potency against axenic amastigotes and intracellular amastigotes of L. donovani significantly, while on para substitution anti-promastigote activity altered marginally. Methoxy, chloro group substitution had strong impact on anti-leishmanial activity of these analogues, position of substitution is vital in their inhibition activity. Ortho substitution of
methoxy group showed excellent increase in inhibition potency against promastigotes and both amastigote forms of L. donovani. While methoxy substitution on ortho position slightly increased the anti-leishmanial activity, meta substitution resulted in drastic decline in activity. Chloro substitution on para and meta position has significantly increased the inhibition potency against tested forms, while on ortho substitution has marginally affected the activity. Meta directing nitro and fluoro substitution on para position haven’t showed any considerable effect on inhibition potency of these analogues.

 

However, fluoro substitution on ortho position and chloro di-substitution (ortho and meta) significantly decreased the anti-leishmanial potency. Replacement of phenyl ring with benzyl ring has significantly enhanced the activity. Even though pyridyl replacement resulted in increased anti-leishmanial activity, it also enhanced the cytotoxicity of these analogues. SAR studies suggested that, ortho-para directing methoxy group on para position, chloro group on para and meta position and benzyl replacement was recommended for anti-leishmanial activity of these analogues against L.
donovani.

 

Through the present study, we have identified new lead molecules with potent anti-leishmaninal activity against L. infantumand L. donovani. Structure activity relationship studies would be utilised to optimize the lead molecules to generate clinically effective against both drug sensitive and resistance strains of L. infantumand L. donovani.
