Abstract
We have developed a copper-catalyzed synthesis of pyrrolo[2,1-a]isoquinolines with terminal alkynes, aldehydes, and tetrahydroisoquinolines. A variety of pyrrolo[2,1-a]isoquinolines have been prepared in 17-69% yield via a condensation/Mannich-type addition/oxidation/cyclization cascade sequence. Modifications through simple chemical transformations provided highly functionalized molecules containing a privileged framework.

Abstract
An efficient copper-catalyzed solvent-free multicomponent reaction for pyridine derivatives, iodonium ylides, and 1,4-quinones is developed via a room-temperature ball milling technique. The reported protocol provides a sustainable synthesis of isoindolo[2,1-a]pyridine/isoquinoline class of molecules in good to excellent yield in a mixer mill (RETSCH MM400) engaging the commercially available copper acetate (Cu(OAc)2) as a catalyst without the use of organic solvents. It tolerates a myriad of electron-rich and electron-deficient functionalities on the pyridine moiety. The scalability of the protocol was illustrated by successfully performing the reaction in the gram scale. The photoluminescence and related cellular study revealed that these can be used as a fluorescent chromophore-based cellular probe. A clean reaction profile and a facile experimental setup that is devoid of anhydrous reaction conditions and toxic organic solvents have established the advantages of this strategy over the reported process.

Abstract
An asymmetric three-component 1,3-dipolar cycloaddition of 3,4-dihydroisoquinolines, bromoacetates and α,β-unsaturated pyrazole amide is realized by using a chiral N,N'-dioxide-Y(OTf)3 complex as the catalyst. The process includes a base-promoted formation of dihydroisoquinolium ylides in situ, and a chiral Lewis acid-catalyzed asymmetric [3+2] cycloaddition with α,β-unsaturated pyrazole amides. A series of hexahydropyrrolo-isoquinolines are obtained in moderate to good yields with excellent diastereo- and enantioselectivities.

Abstract
In quest of promising anticancer agents, the pharmacophores of natural (β-carboline) and synthetic origin (benzothiazole) were adjoined by a carboxamide bridge and three-point diversification was accomplished. The in vitro cytotoxic ability of the compounds was established on adherent and suspension human cancer cell lines and compounds 8u and 8f advanced as pre-eminent molecules with IC50 values of 1.46 and 1.81 μM respectively in A549 cell line. The cytospecificity was entrenched for potent compounds 8u and 8f by evaluating against normal human lung epithelial cells and selectivity index was calculated. Furthermore, EtBr displacement, relative viscosity and gel-based topoisomerase II target assays unveiled the intercalative topo-II inhibitory capability and DNA binding studies (absorbance) revealed the dissociation constant (Kd) for compounds 8u and 8f as 98 and 103 μM respectively. Additionally, cell-based flow cytometric assays like Annexin-V/PI dual staining aids in the quantification of apoptosis induced and JC-1 staining disclosed the depolarization of mitochondrial membrane potential by compound 8u in A549 cells in a dose-dependent manner. Moreover, wound healing assay established the inhibition of in vitro cell migration by compound 8u on A549 cells. In addition, molecular docking studies proved the binding of compounds 8u and 8f in the active site of DNA complexed with topo IIα and stabilized by interactions with DNA base pairs and amino acid residues. Remarkably, the compounds 8u and 8f follow Lipinski's rule of five and are in the recommended range for Jorgensen's rule of three with a minimal violation and other pharmacokinetic parameters revealing druggability of the synthesized hybrids.

Abstract
An expedient and transition-metal-free synthetic strategy has been developed for the construction of substituted indolizines from a unique combination of pyridinium salts and 2-bromoallyl sulfones. This approach does not compromise with the diverse substitutions on both the pyridinium salts and 2-bromoallyl sulfones. Wide substrate scope, operational simplicity, milder reaction conditions and good to moderate yields are the merits associated with the current approach. Moreover, this method provides two products which are amenable for the generation of a library of key indolizine building blocks.

Abstract
Pyrrolo[2,1-a]isoquinoline (PIq) is a nitrogen heterocyclic scaffold of diverse alkaloids endowed with several biological activities, including antiretroviral and antitumor activities. Several 5,6-dihydro-PIq (DHPIq) alkaloids, belonging to the lamellarins' family, have proved to be cytotoxic to tumor cells, as well as reversers of multidrug resistance. In this review, we provide an overview of the main achievements over the last decade in the synthetic approaches to access libraries of PIq compounds along with a survey, as comprehensive as possible, of bioactivity, mechanism of action, pharmacophore and structure-activity relationships of synthetic analogs of DHPIq-based alkaloids. The focus is mainly on the potential exploitation of the (DH)PIq scaffold in design and development of novel antitumor drugs.

Abstract
A Ru(II)-catalyzed regioselective C-H activation toward hydroxymethylation of β-carbolines and isoquinolines as effective directing groups has been developed, and the mechanism was probed by using online electrospray ionization-tandem mass spectrometry. The introduction of the hydroxymethyl group in the biologically relevant molecules routed via C-H functionalization remains an important task. Gratifyingly, this protocol draws attention to the regioselective formation of monohydroxymethylated β-carboline/isoquinoline products exclusively.

Abstract
The functionalized tetrahydrochromeno[4′,3′:2,3]indolizino[8,7-b]indoles were conveniently synthesized in high yields by one-pot domino reaction of tryptamines, alkyl propiolates and 2-aryl-3-nitro-2H-chromenes. Under similar conditions, the one-pot reaction of tryptamines, alkyl propiolates and β-nitroalkenes resulted in functionalized tetrahydroindolizino[8,7-b]indoles. The reaction mechanism involved sequential generation of β-enamino ester, Michael addition, Pictet–Spengler reaction and annulation process. The reaction showed high atomic economy and met the goals of sustainable chemistry. The functionalized tetrahydrochromeno[4′,3′:2,3]indolizino[8,7-b]indoles were conveniently synthesized in high yields by one-pot domino reaction of tryptamines, alkyl propiolates and 2-aryl-3-nitro-2H-chromenes.![]()

Abstract
The title compound, C19H19NO5, (I), is the product of a domino reaction between cotarnine chloride and acetyl-acetylene catalysed by copper(I) iodide. The mol-ecule of (I) comprises a fused tetra-cyclic system containing two terminal five-membered rings (pyrrole and 1,3-dioxole) and two central six-membered rings (di-hydro-pyridine and benzene). The five-membered 1,3-dioxole ring has an envelope conformation and the central six-membered di-hydro-pyridine ring adopts a twist-boat conformation. The acyl substituent is almost coplanar with the pyrrole ring, whereas the meth-oxy substituent is twisted by 27.93 (16)° relative to the benzene ring. The 2-oxopropan-1-yl substituent is roughly perpendicular to the pyrrole ring. In the crystal, mol-ecules are stacked along the a-axis direction; the stacks are linked by weak C-H⋯O hydrogen bonds into puckered layers lying parallel to (001).

Abstract
A series of new phenanthrene-9-benzimidazole conjugates has been synthesized by condensing phenanthrene aldehydes with various substituted o-phenylenediamines. The title compounds were evaluated for their in vitro cytotoxic potential against various human cancer cell lines like breast (BT-549), prostate (PC-3 and DU145), triple negative breast cancer (MDA-MB-453), and human colon cancer (HCT-116 and HCT-15) cells. Among the tested compounds, 10o displayed significant in vitro cytotoxic activity against PC-3 prostate cancer cells with an IC50 value of 6.32 ± 0.09 μM. Further, the cell cycle analysis indicated that it blocks G2/M phase of the cell cycle in a dose dependent manner. In order to determine the effect of the compound 10o on cell viability; phase contrast microscopy, AO/EB staining, DAPI staining, and DCFDA staining studies were performed. In these studies, apoptotic features were clearly observed indicating that the compound inhibited cell proliferation by apoptosis. JC-1 staining and annexin binding assays indicated the extent of apoptosis in PC-3 cells. Further, relative viscosity measurements and molecular docking studies indicated that these compounds bind to DNA by intercalation.
