“…[97] Green synthesis is another aspect particularly carried out using microorganisms and plant extracts [97] like synthesis of D-Sorbitol-cored PAMAM dendrimer (SOR-G1) in presence of ethanol/water system by polymerization of epichlorohydrin giving high yield and good thermal stability. [98] Hundreds of oligonucleotides are functionalized by robotic stamping system on the poly(propylene imine) dendrimers G5 surface as it gives a high density of positively charged surface that can attract negatively charged oligonucleotides in a "layer-by-layer" sequence. [99] Moreover, robotic assisted high-througput system is employed in effective catalytic estimation of metal nanoparticles like palladium and gold polyvinylpyrrolidone nanoparticles.…”

Hybrid dendrimers constitute a unique class of well-defined complex architecture featured with a central domain and bifurcated branches with two different dendritic sequences for their atomic configuration and functional groups at the periphery. This review article pioneers the field of new hybrid dendrimers using different generations by nanoconjugation with metals, carbohydrates, nucleotides, proteins/peptides, carbosilane, urea, silica, stem cells, guanidine, etc. The smart dendrimers contain desirable electrical, magnetic, optical, and biological attributes to increase surface area, monodisperse behavior, dose reduction, dissolution, permeability, longterm stability, and significant decrement in nanotoxicity studies. The higher encapsulation of lipid soluble and insoluble moieties explores an excellent platform for the delivery of drugs (ibuprofen, indomethacin, etc.), nucleic acids (oligonucleotide, siRNA, and aptamer), genetic materials , and chemical diagnostic agents (gadolinium chelates and superparamagnetic iron oxide particles) for imaging. Owing to their flexibility in structural adaptability, different health conditions like glaucoma, inflammation, microbial infection, neurodegenerative problems (Alzheimer's disease and Parkinsonism), and cancer are benefited using such long-lasting drug delivery. Advancements in molecular engineering techniques, 3D printing, artificial intelligence, robotic, green synthesis, and microwave-assisted methods aid in the development of economically reliable and personalized pharmaceutical hybrid dendritic systems resembling antibodies, globular proteins, stem cells, enzymes, and genetic materials.

“…Multi-component reactions have a major role as a green synthetic tool to produce heterocyclic compounds. [1,2] Quinolines are biologically relevant heterocyclic compounds found in a variety of biological systems, including Cinchona alkaloids. [3][4][5] Quinoline derivatives exhibited a wide range of pharmacological activities, including antimalarial, [6] antiasthmatic, [7] antibacterial, [8] analgesic, [9] and anticancer [10] properties, among others.…”

Phloroglucinol cored primary amine-functionalized G0 dendritic polymer (PHGÀ G0) was effectively synthesized. The polymer was characterized by different spectroscopic and analytical techniques including Fourier transform infrared (FT-IR) and Nuclear magnetic resonance (NMR) spectra, Thermogravimetric Analysis (TG-DTG) and Gel Permeation Chromatography (GPC). The catalytic efficiency of the PHGÀ G0 was evaluated in the three-component one-pot green synthesis of quinoline and four component synthesis of polyhydroquinoline derivatives. Quinoline derivatives were obtained 92 % of yield within 60 minutes in water/ethanol (1 : 1) (v/v) mixture as solvent and polyhydroquinoline derivatives were obtained 90 % of yield within 30 minutes in acetonitrile as solvent under reflux conditions. High amino group capacity and high thermal stability made the PHGÀ G0 dendritic polymer a good base catalyst. All the quinoline and polyhydroquinoline derivatives were characterized by determining the melting point, Fourier transform infrared (FT-IR) and Nuclear magnetic resonance (NMR) spectra. The present method is green, efficient, and costeffective. Catalyst can be reused up to four reaction cycles without any characteristic loss of its activity.
