Abstract
A "Core-Linker-Polyamine (CLP)" strategy has been exploited to develop new antileishmanial agents. It involves the linker-based assembly of alkyl-polyamine side chain as a potential pharmacophore motif with a privileged heterocyclic motif, 4-arylquinoline. A series of aminoalkyl 4-arylquinoline-2-carboxamides and their analogs were synthesized and tested against L. donovani promastigotes. Among all synthesized derivatives, 10 compounds showed significant antipromastigote activities with more efficacy (IC 50 : 4.75-8 µ M) than an antileishmanial oral drug Miltefosine (IC 50 : 8.9±1.55 µ M). Most active compounds 9a and 9b , displayed negligible cytotoxicity towards human monocytic (THP-1) macrophages. The compounds show antileishmanial activity by generating mitochondrial superoxide radicals. However, they did not show interference with trypanothione reductase, a redox enzyme of Leishmania. Significant change in the morphology of the L. donovani promastigote by the compounds was observed. The Structure-activity relationship analysis suggest the pharmacophoric importance of alkylpolyamine and carboxamide motifs. In silico evaluation indicated that the investigated active molecules 9a and 9b possess important drug-likeness, physicochemical and pharmacokinetic-relevant properties.

Abstract
Beta-secreatse (BACE-1) and cholinesterases are clinically validated targets of Alzheimer's disease (AD), for which natural products have provided immense contribution. The multifaceted nature of AD signifies the need of multitargeted agents to tackle this disease. In the search of new natural products as dual BACE-1/cholinesterase inhibitors, a library of pure natural products was screened for inhibition of acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and BACE-1. The screening efforts have identified 1,4-benzoquinone "embelin," a natural product derived from Embelia ribes displaying inhibition of all three enzymes, with IC50 values of 2.5, 5.4, and 2.1 μM, respectively. This screen has also identified isoquinoline alkaloids papaverine and L-tetrahydropalmatine as AChE inhibitors. Kinetic study has shown that embelin inhibits EeAChE and EqBChE with ki values of 4.59 and 0.57 μM, in an uncompetitive and noncompetitive manner, respectively. The interactions of embelin with allosteric peripheral anionic site of cholinesterases, has further supported the results of kinetic study. Embelin has also enhanced the activity of P-gp in LS-180 cells, the efflux pump which is involved in the clearance of amyloid-β from AD brain. Further, the cell viability study in neuronal cell line has indicated the excellent therapeutic window of embelin. These results are indicative of the fact that embelin is a multitargeted agent playing role in stopping the formation of amyloid-β oligomers (via inhibition of BACE-1), improves cholinergic-transmission (via inhibition of AChE/BChE) and increases amyloid-β clearance (via P-gp induction).

Abstract
NLRP3 inflammasome is an important therapeutic target for a number of human diseases. Herein, computationally designed series of quinazolin-4(3 H)-ones were synthesized using iodine-catalyzed coupling of arylalkynes (or styrenes) with O-aminobenzamides. The key event in this transformation involves the oxidative cleavage of the C-C triple/double bond and the release of formaldehyde. The reaction relies on the C-N bond formation along with the C-C bond cleavage under metal-free conditions. The nitro-substituted quinazolin-4(3 H)-one 2k inhibited NLRP3 inflammasome (IC50 5 μM) via the suppression of IL-1β release from ATP-stimulated J774A.1 cells.

Abstract
Crocus sativus L. (family: Iridaceae) has been documented in traditional medicine with numerous medicinal properties. Recently, we have shown that C. sativus extract (IIIM-141) displays promising efficacy in a genetic mice (5XFAD) model of Alzheimer's disease (AD) (ACS Chem. Neurosci. 2017, 16, 1756). To translate the available traditional knowledge and the scientifically validated results into modern medicine, herein we aimed to carry out its preclinical development. IIIM-141 is primarily a mixture of crocins containing trans-4-GG-crocin (36 % w/w) as the principal component. The in vitro studies show that IIIM-141 has protective as well as therapeutic properties in assays related to AD. It induces the expression of P-gp, thereby enhancing the amyloid-β clearance from an AD brain. It also inhibits NLRP3 inflammasome and protects SH-SY5Y cells against amyloid-β- and glutamate-induced neurotoxicities. In behavioral models, it decreased the streptozotocin-induced memory impairment in rats and recovered the scopolamine-induced memory deficit in Swiss albino mice at 100 mg/kg dose. The acute oral toxicity study shows that IIIM-141 is safe up to the dose of 2000 mg/kg, with no effect on the body weight and on the biochemical/hematological parameters of the rats. The repeated oral administration of IIIM-141 for 28 days at 100 mg/kg dose did not cause any preterminal deaths and abnormalities in Wistar rats. The pharmacokinetic analysis indicated that after oral administration of IIIM-141, the majority of crocin gets hydrolyzed to its aglycone crocetin. The sustained release (SR) capsule formulation was developed, which showed an improved in vitro dissolution profile and a significantly enhanced plasma exposure in the pharmacokinetic study. The SR formulation resulted in 3.3-fold enhancement in the area under the curve of crocetin and doubling of the crocetin/crocin ratio in plasma compared with the extract. The data presented herein will serve as the benchmark for further research on this botanical candidate.

Abstract
N-(2,2,2-Trifluoroethyl)-N-[4-[2,2,2-trifluoro-1-hydroxy-1-(trifluoromethyl)ethyl]phenyl]-benzenesulfonamide (T0901317, 6) is a potent activator of pregnane-X-receptor (PXR), which is a nuclear receptor controlling P-gp expression. Herein, we aimed to investigate P-gp induction activity of T0901317 and establish its structure-activity relationship. T0901317 along with a series of N-triazolyl-methylene-linked benzenesulfonamides were synthesized and screened for P-gp induction activity using a rhodamine-123 based efflux assay in the P-gp overexpressing human adenocarcinoma LS-180 cells, wherein several compounds showed potent P-gp induction activity at 5 μM. Treatment with benzene sulphonamides led to the decrease in intracellular accumulation of a fluorescent P-gp substrate rhodamine-123 up to 48% (control 100%). In the western-blot studies, T0901317 (6) and its triazole linked analog 26e at 5 μM displayed induction of P-gp expression in LS180 cells. These compounds were non-toxic in LS-180 and human neuroblastoma SH-SY5Y cells (IC50 > 50 μM). The compound 26e showed significant P-gp induction even at 0.3 μM, indicating an excellent therapeutic window. These results clearly indicate promise of this class of compounds as potential agents to enhance amyloid-β clearance in Alzheimers patients.

Abstract
The methanolic extract of the Tanacetum gracile afforded the isolation of new sesquiterpene lactone, named gracilone (1) along with four known compounds as 14α-taraxeran-3-one (2), 14α-taraxeran-3-ol (3), apigenin (4) and β-sitosterol (5). The structure of compound 1 was elucidated on the basis of 1D, 2D NMR and MS spectroscopic analysis. Antimicrobial, antioxidant and anticancer activities of all compounds were evaluated, from which gracilone (1) showed a moderate antibacterial activity, while apigenin (4) showed comparatively more antibacterial activity against both gram-positive and gram-negative tested strains.

Abstract
Multicomponent reactions are a valuable tool for the synthesis of functional π-electron systems. Two different approaches can be taken into account for accessing the target structures. In the more conventional scaffold approach an already existing chromophore is coupled with other components to give a complex functional π-system. Here, electronically monotonous components can also be introduced, which may exert synergistic electronic effects within the novel compound. The more demanding chromophore concept generates a complete π-electron system and a scaffold concurrently. The latter approach is particularly stimulating for methodologists since π-systems might be accessible from simple starting materials. This review encompasses the advances in the preparation of functional π-electron systems via multicomponent processes during the past few years, based both on the scaffold and chromophore concepts. Besides the synthetic strategies the most important properties, i.e. redox potentials, absorption and emission maxima or fluorescence quantum yields, of the synthesized molecules are highlighted.

Abstract
Colchicine (1), a nature-derived microtubule polymerization inhibitor, develops multi-drug resistance in tumor cells due to its P-gp substrate and induction activity, which in turn leads to its rapid efflux from tumor cells. This auto-induction of the efflux of colchicine remains a major challenge to medicinal chemists. Based on structure-based molecular modeling, a series of new colchicine derivatives were designed and synthesized with a potential for reduced P-gp induction liability. Screening of the prepared derivatives for P-gp induction activity revealed that a number of derivatives possess remarkably lower P-gp-induction activity (>90% intracellular accumulation of rhodamine 123 in LS-180 cells) compared to the parent natural product colchicine (62% Rh123 accumulation in LS-180 cells). The reduced P-gp-induction activity of new derivatives may be due to their reduced ability to interact and change the conformation of P-gp. The synthesized derivatives were then screened for antiproliferative activity against two colon cancer cell lines including HCT-116 and Colo-205. The derivative 4o showed potent cytotoxicity in HCT-116 cells with IC50 of 0.04 μM with significantly reduced P-gp induction liability. Compound 4o also inhibited microtubule assembly and induced expression of pro-apoptotic protein p21. In an Ehrlich solid tumor mice model, compound 4o showed 38% TGI with no mortality at 2 mg kg(-1) dose (oral). Compound 4o, with potent in vitro and in vivo anticancer activity, significantly reduced P-gp induction activity and its excellent physicochemical and pharmacokinetic properties open up new opportunities for the colchicine scaffold.

Abstract
An expedient and metal-free synthetic protocol for construction of substituted quinolines has been developed from anilines and phenylacetaldehydes using imidazolium cation-based ionic liquids as the reaction medium. Mechanistic analysis indicated that the reaction occurs through C-C and C-N bond formation to produce isolable 2,3-disubstituted quinoline intermediates, which undergo C-C bond cleavage to produce 3-substituted quinolines. The reaction proceeds smoothly with a range of functionalities in good to excellent yields. Advantages of this protocol include metal-free, environmentally friendly, recyclable reaction media, higher yields and shorter reaction times, and thus is promising for the efficient combinatorial synthesis of structurally diverse 2,3-disubstituted and 3-substituted quinolines.
