Abstract
We report herein a highly efficient and mild approach for synthesizing pharmacologically active bis(indolyl)methanes 3a-z, utilizing ZrO2 nanoparticles as a catalyst. The method involves a condensation reaction between indole and diverse aromatic aldehydes in acetonitrile under mild conditions. The ZrO2 nano-catalyst prepared via a co-precipitation method demonstrates exceptional efficacy, leading to favourable yields of the target bis(indolyl)methanes 3a-z. The versatility of this methodology is highlighted through substrate screening, showcasing its applicability to various aromatic aldehydes.

Abstract
Bis(indolyl)methane skeleton is the main building block of many naturally occurring bioactive compounds. Bis(indolyl)methanes are found to possess a wide range of pharmaceuitical efficacies. These important scaffolds are being used as anti-cancer, antioxidant, anti-bacterial, anti-inflammatory, and anti-proliferative agents. In this review, we summarized the latest developments on the synthesis of various bis/tris(indolyl)methane derivatives from the reactions of two equivalents of indoles and one equivalent of aldehydes or indole-3-carbaldehydes under various reaction conditions. More than hundred different catalysts were employed for these transformations which include various metal catalysts, ionic liquids, organocatalysts, surfactants, homogeneous, heterogeneous catalysts etc.

Abstract
This article describes discovery of 29 novel bisindolylmethanes consisting of thiourea moiety, which had been synthesized through three steps. These novel bisindolylmethane derivatives evaluated for their potential inhibitory activity against carbonic anhydrase (CA) II. The results for in vitro assay of carbonic anhydrase II inhibition activity showed that some of the compounds are capable of suppressing the activity of carbonic anhydrase II. Bisindoles having halogen at fifth position showed better inhibitory activity as compared to unsubstituted bisindoles. Derivatives showing inhibition activity docked to further, understand the binding behavior of these compounds with carbonic anhydrase II. Docking studies for the active compound 3j showed that nitro substituent at para position fits into the core of the active site. The nitro substituent of compound 3j is capable of interacting with Zn ion. This interaction believed to be the main factor causing inhibition activity to take place.

Abstract
Bisindole analogs 1-17 were synthesized and evaluated for their in vitro β-glucuronidase inhibitory potential. Out of seventeen compounds, the analog 1 (IC50=1.62±0.04 μM), 6 (IC50=1.86±0.05 μM), 10 (IC50=2.80±0.29 μM), 9 (IC50=3.10±0.28 μM), 14 (IC50=4.30±0.08 μM), 2 (IC50=18.40±0.09 μM), 19 (IC50=19.90±1.05 μM), 4 (IC50=20.90±0.62 μM), 7 (IC50=21.50±0.77 μM), and 3 (IC50=22.30±0.02 μM) showed superior β-glucuronidase inhibitory activity than the standard (d-saccharic acid 1,4-lactone, IC50=48.40±1.25 μM). In addition, molecular docking studies were performed to investigate the binding interactions of bisindole derivatives with the enzyme. This study has identified a new class of potent β-glucouronidase inhibitors.

Abstract
Gramine-MeI salts were useful starting materials for the synthesis of 3-benzyl- and 3-allylindoles by the 1,4-addition of boronic acids to the C=C-C=N linkages generated in situ under Rh(I)-catalysis. On the other hand, under Ir(I) catalysis, the reaction of gramines with indoles was used to produce nonsymmetrical diindolylmethanes. [reaction: see text]

Abstract
An efficient method for the preparation of bis-indolylmethanes and bis-indolylglycoconjugates from carbonyl compounds with indoles in the presence of a catalytic amount of iron(iii) fluoride under solvent-free conditions is reported. The desired products were obtained in high yields with a simple and environmentally benign procedure. The use of iron(iii) fluoride is feasible because of its stability, easy handling, easy recovery, reusability, and good activity.

Abstract
Bis(3'-indolyl)alkanes and bis(3'-indolyl) derivatives containing a 1-deoxyalditol moiety were synthesized in the presence of 5 mol% of scandium(III) trifluoromethanesulfonate [Sc(OTf)3] in CH3CN or EtOH-H2O mixture as a solvent from room temperature to 70 degrees C in good yields (78-97%).

Abstract
Many tryptamine derivatives are known to induce altered states of consciousness and are increasingly of interest in forensic and neurobiological studies. The analytical chemistry of certain synthetic routes to the tryptamines is discussed and likely side products and impurities identified, where literature reports are available. Recent examples from the authors' laboratory are presented to highlight future prospects and implications for analytical procedures. The aim of this review is to provide the analytical chemist with the foundation chemistry and some analytical targets to be able to undertake direct characterisation of products and intermediates. These might become available from interdiction of clandestine operations in a forensic environment or during the synthesis of the tryptamines for investigative neurobiological and clinical procedures.
