Summary: A convenient strategy for the synthesis of pyrroles lineary linked to 4H-pyrrolo[3,2,1-ij]quinolin-2(1H)-ones is presented. The cyclization of (E)-1-(2-oxo-2-phenylethylidene)-4H-pyrrolo[3,2,1-ij]quinolin-2-ones with linear and cyclic enaminones proceeds both in the presence of p-toluenesulfonic acid and triethylamine. The obtained compounds are characterised by atropoisomerism and keto-enol tautomerism. The synthesized 1-(2-phenyl-1H-pyrrol-3-y1)-4H-pyrrolo[3,2,1-ij]quinolin-2(1H)-ones were studied for anticoagulant activity.

Summary: Despite extensive research, the prevention of blood clots remains an important area of study. Novel pyrroloquinolinedione-based rhodanine derivatives were synthesized and evaluated as potential molecules to inhibit clotting factors Xa and XIa. In vitro testing showed that these derivatives have the potential anticoagulant activity by inhibiting both coagulation factors Xa and XIa.

Summary: The aldol addition of acyclic and cyclic ketones to 4,4,6-trimethyl-4H-pyrrolo[3,2,1-ij]quinoline-1,2-diones and the reduction of the diones with sodium tetra-hydridoborate produced 1-substituted 1-hydroxy-4,4,6-trimethyl-4H-pyrrolo[3,2,1-ij]quinolin-2(1H)-ones efficiently in a short time.

Summary: 1,3-Oxazino[5,4,3-ij]quinolin-1,3-diones were obtained in good yields (64-86%) by oxidizing various pyrrolo[3,2,1-ij]quinoline-1,2-diones with m-chloroperbenzoic acid. The recyclization/rearrangement of the pyrroldione fragment of the starting materials selectively leads to the formation of a 1,3-oxazine cycle instead of an isomeric 1,4-oxazine ring.

Summary: The bromination of allylic bromide in 4,4,6-trimethyl-4H-pyrrolo[3,2,1-ij]quinoline-1,2-diones was studied using N-bromosuccinimide (NBS) in carbon tetrachloride and DMF solution. Regioselective bromination occurred at the methyl group at position 6 when using equimolar NBS in the BPO-CCl4 system, resulting in the formation of 6-bromomethylene derivatives. In the NBS-DMF system, monobromination occurred at position 5 with allylic bond rearrangement. With a twofold excess of NBS, a (Z)-5-bromo-6-bromomethylene derivative was formed in both cases. The isomers of 5-monobromine underwent retro-allylic rearrangement in N- and S-alkylation reactions, yielding exclusively 6-N-alkyl and 6-S-alkyl derivatives, respectively. Similar products were obtained from reactions using 6-bromomethylene derivatives.

Summary: In this study, tetrahydro-4H-pyrrolo[3,2-c]quinolin-4-ones and dihydro-1H-benzo[b]azepines were efficiently synthesized from 2-aminobenzonitriles and donor-acceptor cyclopropanes using SnCl4 as a catalyst. The reaction involves cyclopropane ring opening and nucleophilic attack by amine, followed by unprecedented rearrangement at two different reaction temperatures, resulting in the formation of two nitrogen heterocycles. This methodology can be used for the synthesis of hexahydropyrrolo[3,2-c]quinolinone derivatives, which are present in biologically active molecules.

Summary: A series of substituted 1,3,4-subtituted-pyrrolo[3,2-c]quinoline derivatives (PQs) were evaluated for their anticancer activity against a panel of tumor cells. The optimized derivatives showed promising activity with increased potency against multiple tumor cell lines, including leukemia, CNS, melanoma, renal, and breast cancer. Further investigations were conducted on breast cancer cells, revealing potential targets for optimization, including HSP90 and ER receptors.

Summary: A regioselective synthesis of novel 2H,3H-[1,4]thiazino[2,3,4-ij]quinolin-4-ium derivatives was achieved by annulation reactions, using 8-quinolinesulfenyl bromide as a reagent. The reactions with different vinyl chalcogenides and tetravinyl silane showed opposite regiochemistry, resulting in water-soluble functionalized compounds with potential biological activity.

Summary: In this study, pyrrolo[2,3-d]pyrimidine-2-amine derivatives (4a-n) were synthesized using pyrrolo[2,3-d]pyrimidine, potassium amide, and liquid ammonia. The structure of these compounds was determined using spectroscopic techniques and elemental analyses. The synthesized compounds were evaluated for their cytotoxic activity against human cancer cell lines, and moderate to significant cytotoxic effects were observed. Further investigation revealed that some compounds displayed inhibitory effects on epidermal growth factor receptor tyrosine kinase (EGFR-TK), making it a potential target for novel anticancer drug development. All compounds complied with Lipinski's rule of five, indicating their potential as oral drug candidates.

Summary: Using a combination of physical and electrochemical methods, this study examined the influence of R-substituent on the adsorption of 5-R-3-amino-1,2,4-triazoles on copper surfaces in neutral buffer solution. The research identified minimum concentrations that suppress copper dissolution and determined free adsorption energies for different types of compounds based on the R-substituent. The results showed that the adsorption characteristics of triazoles were dependent on the nature of the substituent, with electron acceptor R resulting in higher adsorption at lower concentrations.
