Abstract
A catalyst-free synthetic route to a new 1,2,4-triazole-pyrrolo[1,2-a]pyrazine hybrid system, 6-acylpyrrolo[1,2-a][1,2,4]triazolo[5,1-c]pyrazine, was realized upon sequential exposure of pyrrole-2-carbonitrile-derived substrates to DMF-DMA and acyl hydrazide through which acylated pyrazine and 1,2,4-triazole rings were consecutively formed with the formation of multiple bonds (one C-C bond and three C-N bonds). This annulative functionalization approach towards N-fused polycycles enabled us to install various substituents at specific positions on the core skeleton.

Abstract
Cerebral amyloid-β (Aβ) deposition is a representative hallmark of Alzheimer's disease (AD). Development of Aβ-clearing small molecules could be an advantageous therapeutic strategy for Aβ clearance considering the advantages in terms of side effects, cost-effectiveness, stability, and oral bioavailability. Here, we report an Aβ-dissociating small molecule, YIAD-0121, a derivative of 4-acyl-3,4-dihydropyrrolo[1,2-a]pyrazine. Through a series of anti-Aβ screening assays, YIAD-0121 was identified to inhibit Aβ aggregation and dissociate preformed Aβ fibrils in vitro. Furthermore, the administration of YIAD-0121 in 5XFAD transgenic AD mice inhibited the increase of cerebral Aβ aggregation and progression of hippocampus-dependent cognitive decline, with ameliorated neuroinflammation.

Abstract
A new pyrrolo[1,2-a]pyrazine chemical space with a poly-substituted pyrazine unit was readily accessed by Sc(OTf)3-catalyzed one-pot three-component coupling of a pyrrole derivative, amine, and trialkylphosphite under environment-friendly conditions. The formation of multiple bonds (two C-N and one C-P) via a domino process consisting of the chemoselective Kabachnik-Fields reaction and intramolecular cyclodehydration allowed for the construction of highly functionalized pyrazines.

Abstract
A new one-pot, sequential three-component access to 3,4-diacylpyrrolo[1,2-a]pyrazine was achieved from the reaction of an α-haloketone, azide, and N-substituted pyrrole-2-carboxaldehyde under mild reaction conditions, through which a polysubstitution pattern on the pyrazine moiety of the scaffold was realized. The formation of multiple bonds (one C-C and two C-N) was enabled by this domino process involving the in situ generation of α-iminoketones, intermolecular Mannich reaction, intramolecular imine formation, and aromatization. Construction of the relevant 3,4-diacylpyrazino[1,2-a]indole and further expansion of this chemical space via synthetic elaboration of the resulting products were demonstrated as well. Preliminary biological screening of the synthesized derivatives against oral adenosquamous carcinoma cells (CAL-27) and triple negative human breast cancer cells (MDA-MB-231) led us to identify a potent hit compound (7o) having ∼3 times stronger in vitro anticancer activity than that of the anticancer agent, capecitabine.

Abstract
A highly efficient synthetic route to new quinone-indolizine hybrids was accomplished from quinones and N-substituted pyrrole-2-carboxaldehydes via a domino Michael addition-aldol condensation-aromatization sequence through which the central pyridine ring was constructed in atom-economical and environment-friendly manner. Post modification of the resulting products was also demonstrated, enabling further expansion of this heterocyclic chemical space. Biological evaluation of the quinone-indolizine hybrids revealed potent anticancer effects in human prostate adenocarcinoma cells (PC-3) and oral adenosquamous carcinoma cells (CAL-27).

Abstract
Due to a growing interest in aza-fused polyaromatic systems among various sciences, enormous attention has been continuously paid to design and synthesize novel chemotypes of N-fused heterocycles. During the course of continued efforts in this line, it was found that divergent access to new polycyclic N-fused heteroaromatics was enabled by choice of reaction solvent. Described herein are solvent-controlled selective approaches to three novel N-fused azacycles, benzo-[d]imidazole-pyrrolo[1,2-a]pyrazine hybrids, under mild conditions. The plausible reaction mechanism for each class of compound is suggested as well.

Abstract
Chemical territory bearing a 2,2-dimethyl-2H-chromene motif was expanded by utilizing an o-hydroxy aldehyde group of 5-hydroxy-2,2-dimethyl-2H-chromene-6-carbaldehyde as a synthetic handle to install distinctive morphology and functionality of each scaffold. Cell based assays and in silico docking analysis led us to discover that these new compounds exhibit inhibitory effect on anoctamin1 (ANO1). ANO1 is amplified and highly expressed in various carcinomas including prostate cancer, esophageal cancer, breast cancer, and pancreatic cancer. Biological assays revealed that (E)-1-(7,7-dimethyl-7H-furo[2,3-f]chromen-2-yl)-3-(1H-pyrrol-2-yl)prop-2-en-1-one (3n, Ani-FCC) is a novel, potent and selective ANO1 inhibitor with an IC50 value of 1.23 μM. 3n showed 144 times stronger activity on ANO1 inhibition than ANO2 inhibition and did not alter the chloride channel activity of CFTR and the intracellular calcium signaling. Notably, 3n strongly decreased cell viability of PC-3 and FaDu cells expressing high levels of ANO1 with a decrease in ANO1 protein levels. In addition, 3n significantly enhanced apoptosis via activation of caspase 3 and cleavage of PARP in PC-3 and FaDu cells. This study shows that a novel ANO1 inhibitor, 3n, can be a potential candidate for the treatment of cancers overexpressing ANO1, such as prostate cancer and esophageal cancer.

Abstract
A modular approach to polycyclic N-fused heteroaromatics is described. Acid-catalyzed reactions of various 1-(2-oxo-2-arylethyl)-1H-pyrrole-2-carbaldehydes with several o-phenylenediamines provided facile access to a number of new benzo[d]imidazole-pyrrolo[1,2-a]pyrazine hybrid structures through double cyclodehydration and aromatization. Optical characterization of the synthesized compounds revealed unique emission properties, with deep blue emission in the aggregated and solid states, and a dramatic substituent effect was observed. Fusion of an additional benzene ring into the benzo[4,5]imidazo[1,2-a]pyrrolo[2,1-c]pyrazine scaffold resulted in a remarkable increase in the intensity of blue fluorescence from the solution along with good cell permeability and negligible phototoxicity, indicating the potential for bioimaging applications. A modular approach to polycyclic N-fused heteroaromatics is described.![]()

Abstract
In connection with our continued research to generate new aza-fused heteroaromatic chemical scaffolds, we developed a highly atom-economical three-component route to novel 3,4-dihydropyrrolo[1,2-a]pyrazine ring skeleton multi-functionalized on the pyrazine unit. This [4+1+1] annulation approach led us to gain access to a new N-fused bicyclic chemical space having two distinctive functional groups (heteroaryl and aroyl) in a trans manner. Investigation of anticancer activity of the synthesized compounds and their derivatives revealed that (3R*,4S*)-3-(4-bromophenyl)-4-(4-fluorobenzoyl)-2-(2-oxo-2-phenylethyl)-3,4-dihydropyrrolo[1,2-a]pyrazin-2-ium bromide (3h) has potent anticancer activity. 3h significantly inhibited cell viability in prostate cancer cells (PC-3) and breast cancer cells (MCF-7) with IC50 value of 1.18 ± 0.05 μM and 1.95 ± 0.04 μM, respectively. In addition, 3h strongly reduced cell migration in a dose dependent manner, and induced apoptosis via caspase-3 activation and cleavage of PARP in PC-3 and MCF-7 cells. Our results in this study imply that 3h can be a potential anticancer agent against prostate cancer and breast cancer.
