, p. 595 - 600 (2004)
In this study, eight new ω-(1H-imidazol-1-yl)-N-phenylacetamide and propionamide derivatives having 2,6-dimethyl, 2,6-dichloro, 2-chloro-6-methyl and 2-isopropyl substitutions on N-phenyl ring were synthesized to evaluate anticonvulsant activity against maximal electroshock test. The most active compounds in the series were the derivatives bearing 2-isopropyl and 2,6-dimethyl substituents on N-phenyl ring.

Pancreatic cancer is one of the most challenging diseases with seven months only as median survival time due to its poor prognosis. Several enzymes are blamed for the progress of pancreatic cancer especially, platelet-derived growth factor receptors (PDGFRs), this in turn makes them promising targets for its treatment. In this study, twenty eight new compounds based on thieno[2,3-d]pyrimidine scaffold were synthesized as anti-pancreatic cancer agents mimicking the benzofuro[3,2-d]pyrimidine derivative, amuvatinib. Various linkers including amides, esters, ketones, urea and thiourea derivatives were utilized to study their effect on the anti-proliferative activity of these compounds. Most of the tested compounds revealed good cytotoxic activities against pancreatic carcinoma cell line PANC-1. Compound 9d showed the highest cytotoxicity with an IC50 value of 5.4 μM. Furthermore, 9d showed excellent platelet derived growth factor receptor (PDGFR-α) inhibitory activity, with IC50 value 0.155 μM. Docking study was carried out into PDGFR-α active site which showed comparable binding mode to that of FDA approved PDGFR-α inhibitor, imatinib. 3D-Quantitative structure activity relationship (QSAR) model was built up with five-featured pharmacophore which could be implemented for emerging effective lead structures. These compounds could serve as a new chemotype for discovering new agents for pancreatic cancer therapy.

Design, Synthesis and Computational Studies of Novel Carbazole N-phenylacetamide Hybrids as Potent Antibacterial, Anti-inflammatory, and Antioxidant Agents
Pattanashetty, Shivarudrappa H.,Hosamani,Shettar, Arun Kashivishwanath,Mohammed Shafeeulla
, p. 1765 - 1774 (2018)
The present study deals with the synthesis of N-phenylacetamide-functionalized carbazole derivatives and their antibacterial, anti-inflammatory, and antioxidant assays. In vitro antibacterial studies of synthesized compounds shows prominent activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa. In addition, in silico molecular docking studies corroborated that the methyl substituent (3g), (3h), and (3i) showed promising activity with lower ?G (kcal/mol) values. This study envisages that these compounds can serve as a new leading template in the chemotherapy of various bacterial ailments.

In an endeavour to develop efficacious antiprotozoal agents 2-[4-(7-chloroquinolin-4-yl)piperazin-1-yl]acetamide derivatives were synthesized and screened in vitro against the HM1:IMSS strain of E. histolytica and 3D7 strain of P. falciparum. Among the twenty-seven synthesized compounds, eleven evinced propitious anti-amoebic activity with IC50 values ranging from 0.41 to 1.80 μM) lower than the standard drug metronidazole (IC50 1.80 μM). All the compounds inhibited the in vitro growth of P. falciparum (IC50 range: 0.30-33.52 μM). Compounds A22 and A25 were found to be the most active antimalarial derivatives, and compound A16 the most active in inhibiting β-haematin formation; however compound A25 displayed the more favourable safety profile. The crystal structure for the compounds A7, A8, A12 and A21 was also determined. The molecular docking of crystal resolved inhibitors with PfDHFR allowed identification of stabilizing interactions within enzyme active sites. These compounds affirm the potential for further derivatives to enhance antiprotozoal activity whilst retaining their safety profile.

Two different classes of ruthenium complexes, namely, [1-mesityl-3-(2,6-Me2-phenylacetamido)-imidazol-2-ylidene]Ru(p-cymene)Cl (1c) and {[1-(pyridin-2-ylmethyl)-3-(2,6-Me2-phenyl)-imidazol-2-ylidene]Ru(p-cymene)Cl}Cl (2c), successfully catalyzed the one-pot tandem alcohol-alcohol coupling reactions of a variety of secondary and primary alcohols, in moderate to good yields of ca. 63-89%. The mechanistic investigation performed on two representative catalytic substrates, 1-phenylethanol and benzyl alcohol using the neutral ruthenium (1c) complex showed that the catalysis proceeded via a partially reduced CC hydrogenated carbonyl species, [PhCOCH2CH2Ph] (3′), to the fully reduced CO and CC hydrogenated secondary alcohol, [PhCH(OH)CH2CH2Ph] (3). Furthermore, the time dependent study showed that the major product of the catalysis modulated between (3′) and (3) during the catalysis run performed over an extended period of 120 hours. Finally, the practical utility of the alcohol-alcohol coupling reaction was demonstrated by preparing five different flavan derivatives (13-17) related to various bioactive flavonoid natural products, in a one-pot tandem fashion.

(2-Chloroquinolin-3-yl)-1,3,4-thiadiazole-2-carboxamides were synthesized from hydrazones obtained via the reaction of 3-formyl-2-chloroquinoline with oxamic acid thiohydrazides.
