Series of 1-(N-phenyl-2-(heteroalicyclic-1-yl)acetamido)cyclohexane-1-carboxamide derivatives (5a-m) and 1-(phenyl(heteroalicyclic-1-ylmethyl)amino)cyclohexane-1-carboxamide (6a-f) were designed and synthesized with biological interest through coupling of 1-(2-chloro-N-phenylacetamido)cyclohexane-1-carboxamide (4) and (phenylamino)cycloakanecarboxamide (2) with different amines. The structures of the target compounds were elucidated via IR, 1H and 13C NMR, MS, and microanalysis. Compounds 5a-m and 6a-f were evaluated for their in vitro antitumor activity against four different cancer cell lines, MCF-7, HepG2, A549, and Caco-2. Compound 5i exhibited a promising activity against breast cancer cell line (IC50 value = 3.25 μM) compared with doxorubicin (IC50 value = 6.77 μM). Results from apoptosis and cell cycle analysis for compound 5i revealed good antitumor activity against MCF-7 cancer cell line and potent inhibition.

Novel 1,1-disubstituted cyclohexane-1-carboxamides 6a-h, 7a-e, and 8a-b were designed and synthesized as apoptotic inducers. Cytotoxicity test revealed that some compounds have strong to moderate effect, while others displayed weak action against different cancer cell lines including, MCF-7, HepG2, A549, and HTC-116. A549 carcinoma cell line exhibited higher sensitivity toward all synthesized candidates especially compounds 6a and 8a which offered the lowest IC50 values 3.03 and 5.21 μM, respectively, relative to the positive control doxorubicin with IC50 value of 3.01 μM. Compared to doxorubicin treatment, compounds 6a and 8a induced caspases-3, -8, and -9 activities and G2/M growth arrest in A549 carcinoma cell line. The expression levels of p53 (tumor suppressor protein that in humans is encoded by the TP53 gene), Bax (apoptosis regulator protein in humans that is encoded by bax gene), and the Bax/Bcl-2 ratio were all higher than those in doxorubicin-treated cells (Bcl-2, B-cell lymphoma 2, encoded in humans by the Bcl-2 gene). Additionally, compounds 6a and 8a appeared to exhibit higher selectivity against MCF-10 human breast normal cell line. The synthesized congeners could be considered as potent apoptotic inducers interfering with extrinsic and intrinsic apoptotic pathways. Moreover, compound 6a was able to form complex with zinc ions as indicated by UV spectrophotometry which revealed its ability for being caspase activator. Molecular docking studies expected the interactions and binding modes of the synthesized inhibitors in the caspase-3 active site.

Abstract: A new multifunctional bimetallic nanocatalyst was prepared by immobilization of Cu/Ni-doped sulfated zirconium oxide on magnetic cadmium ferrite (CdFe2O4@SiO2@ZrO2/SO42?/Cu/Ni) and used as an efficient recyclable catalyst for one-pot as well as stepwise preparation of α-aminonitriles under mild conditions. The magnetic nanocatalyst was characterized by FTIR, TGA, VSM, XRD, EDX, FE-SEM, and TEM analyses. Also, the surface acidity of the catalyst was measured by pyridine adsorption assay. The catalyst possesses various active sites which could catalyst a variety of aromatic and aliphatic aldehydes to the corresponding α-amionitriles under moderate to high yields in the presence of aniline. Furthermore, transformation of ketones to the desired α-amionitriles and some bis-aminonitriles was also performed by this method. The catalyst could be readily recovered from the reaction mixture and reused for several times without significant loss of activity. Graphic abstract: A general and efficient method has been developed for transformation of a variety of aliphatic, aromatic aldehydes and ketones to the corresponding α-aminonitriles using a multifunctional recyclable CdFe2O4@SiO2@ZrO2/SO42?/Cu/Ni nanocatalyst.[Figure not available: see fulltext.]

Fe3O4@SiO2–APTES-supported trifluoroacetic acid nanocatalyst was used for the one-pot synthesis of α-aminonitriles via a three-component reaction of aldehydes (or ketones), amines, and sodium cyanide. This method produced a high yield of 75–96% using only a small amount of the catalyst (0.05?g) in EtOH at room temperature. The catalyst was also employed for the synthesis of 5-substituted 1H-tetrazoles from nitriles and sodium azide in EtOH at 80°C. The tetrazoles were produced with good-to-excellent yields in a short reaction time of 4?h. Both synthetic methods were carried out in the absence of an organic volatile solvent. Because the supported trifluoroacetic acid generated a solid acid on the surface, thus the acid corrosiveness was not a serious challenge. This heterogeneous nanocatalyst was magnetically recovered and reused several times without significant loss of catalytic activity.

Abstract: Gallic acid-coated magnetic nanoparticles were efficiently prepared, characterized by Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometry, scanning electron microscopy, and transmission electron microscopy, and employed as an environmentally friendly and recyclable catalyst for one-pot synthesis of three-component reaction via Strecker reaction, incorporating aldehydes/ketones, amines, and trimethylsilyl cyanides under solvent-free conditions. Operational simplicity, product purity, natural resources and reusability of the catalyst are considered as evident features of this protocol which will hopefully develop into an inexpensive, efficient, and clean strategy for the synthesis of α-aminonitriles.

Abstract: Good to excellent yields of α-aminonitriles are achieved through three-component Strecker reaction of aldehydes or ketones with amines and trimethylsilyl cyanides over homopiperazine sulfamic acid functionalized mesoporous silica nanoparticles (MSNs-HPZ-SO3H).
