Abstract
Facile synthesis of micellar “nano” indole heterocyclic anti-cancer compounds is described. The synthesized compounds (11–23) were characterized by UV-VIS, 1H NMR, FT-IR and mass spectroscopy. The binding energies of DNA–compound adducts varied from −20.08 to −23.85 kJ mol−1, and they were stabilized by hydrophobic interactions and H-bonding. The synthesized compounds enter into minor grooves of DNA during adduct formation. The DNA binding constant of compounds 11–23 was 1.00 to 2.00 × 105 M−1. The drug-loading efficiency and drug-loading content in their micellar forms were recorded. Compounds 11, 12, 14 and 19 at a micellar concentration of 670 μL mL−1 displayed excellent anticancer activities against the HepG2/C3A line (25–50%). The potency of nano anticancer drugs was predicted by drug likeness using Lipinski's “rule of five”. Taken together, compounds 11–23 could be used to treat cancers. Facile synthesis of micellar “nano” indole heterocyclic anti-cancer compounds is described.![]()

Abstract
A concise, atom-economic strategy for the synthesis of pyrrolizines with amino and keto substituents has been developed. It includes the following key steps: (i) the base-catalyzed (K3PO4/DMSO) addition of a benzylamine to 2-acylethynylpyrroles and (ii) noncatalyzed addition of enaminones obtained to the triple bond of acylacetylenes followed by intramolecular cyclization of the intermediate pentadiendiones thus formed to the target 1-(benzylamino)-2-acyl-3-methylenoacylpyrrolizines.

Abstract
We describe here a tandem catalytic route to prepare imidazoles in a single operation from aryl iodides, imines and CO. The reaction involves a catalytic carbonylation of aryl halides with imines to form 1,3-dipoles, which undergo spontaneous 1,3-dipolar cycloaddition. Overall, this offers an alternative to coupling reactions to construct the (hetero)aryl-imidazole motif, where variation of the building blocks can allow the synthesis of broad families of imidazoles with independent control of all substituents.

Abstract
Imidazole ring is an important five-membered aromatic heterocycle that is widely present in natural products and synthetic molecules. The isocyanide-isocyanide [3+2] cross-cycloaddition reaction constitutes a straightforward method to access imidazoles starting from the easily available chemicals. So far, only three successive reports are known and all lead to the formation of 1,4-disubstituted imidazoles. Here, we report the first isocyanide-isocyanide [3+2] cross-cycloaddition reaction allowing for the formation of 1,4,5-trisubstituted imidazoles under silver catalysis. An unexpected 1,2-migration of sulfonyl, alkoxycaybonyl, and carbamoyl groups took place during the cyclization process that is responsible for the formation of trisubstituted imidazoles. This report displayed a mechanistically novel synthetic method toward a variety of imidazole derivatives, which are otherwise difficult to access by conventional methods.

Abstract
An efficient one-pot synthesis of a series of diversely functionalized trisubstituted 4(5)het(aroyl)-2,5(4)-het(aryl)/alkylimidazoles from readily available 1,3-bishet(aryl)monothio-1,3-diketones has been reported. This novel sequential one-pot, three step protocol, wherein three new carbon nitrogen bonds are formed in contiguous fashion, involves in situ generation of enaminones by reaction of monothio-1,3-diketones with α-substituted methylamines, followed by their α-nitrosation with sodium nitrite and subsequent base mediated intramolecular heterocyclization of the resulting α-hydroxyiminoimines to trisubstituted imidazoles in high yields under mild conditions. These newly prepared 4(5)-het(aroyl)-5(4)-het(aryl)/alkylimidazoles are shown to exist as tautomeric mixture, however, their subsequent alkylation with methyl iodide in the presence of potassium carbonate affords 1-N-methy-2,5-bishet(aryl)-4-het(aroyl)imidazoles in highly regioselective fashion in most of the cases. Synthesis of few 4(5)-(2-hydroxyphenyl)-2,5(4)-substituted imidazoles, which are known to be good coordinating ligands, has also been reported. A probable mechanism for the formation of these imidazoles from hydroxyiminoimine intermediates has also been suggested.

Abstract
An understanding of the mechanism by which minor groove binding agents interact with DNA has led to the design of agents that can reversibly bind with high selectivity to extended DNA target sequences. Simple compounds, such as the polypyrroles and the bis-benzimidazoles, have been used as carriers for alkylating agents effectively directing alkylation to specific DNA sequences. The spectrum of DNA alkylation and mutation by classical alkylators, such as nitrogen mustards, has been profoundly modified by such attachment. The observed "side-by-side" binding of small polypyrrole antibiotics has led to the design of synthetic hairpin polyamides with programmable DNA sequence selectivity. These compounds are able to compete with natural substrates, such as specific transcription factors, and alter gene expression. They are being developed as artificial transcription factors, able to deliver activating peptides to specific recognition sequences, and as potential protein-DNA dimerization agents. Hairpin polyamides are also being used as carriers for the delivery of alkylators to defined DNA sites. The degree of control of gene expression thus offered by the hairpin polyamides suggests enormous promise for their clinical utility. Recent developments with other minor groove binding small molecules and technological advances are also discussed.
