Deciphering Khalil Gibran's 'Sharākh Al-Qubūr': A Structural Insight

Examining the structure of a narrative is crucial for readers to comprehend the literary work and gain insights into the author's writing techniques. This research focuses on analyzing the textual structure of Khalil Gibran's short story 'صراخ القبور' (The Cry of the Graves), encompassing plot, themes, characters, and setting. Utilizing a qualitative approach and structuralism analysis techniques, the study employs library research methods. The data analysis reveals that the theme revolves around justice. The plot exhibits a non-linear progression, and the main character is the 'I' character, supported by three other characters. The setting is described extrinsically, incorporating both time and place. The narrative utilizes multiple points of view. Each intrinsic element within the story is interconnected, forming a cohesive and integrated meaning

SYNTHESIS, ANTICANCER ACTIVITY AND MOLECULAR DOCKING STUDY OF NOVEL 1, 3-DIHETEROCYCLES INDOLE DERIVATIVES

Objective: The present work aimed to synthesize some new 1, 3-diheterocyles indolyl derivatives and study their cytotoxic activity. In addition, explore the probability of the most promising antiproliferative compounds to inhibit TopoI enzyme theoretically via molecular docking study.Methods: Reaction of ethyl 2-(3-formyl-1H-indol-1-yl)acetate (1) with 2-cyanoacetic acid hydrazide, 3-amino-5-pyrazolone and 2'-acetyl-2-cyanoacetohydrazide in an equal molar ratio led to the formation of compounds 2, 6, 8 and 10, respectively, which in turn reacted with another molecule of 2-cyanoacetic acid hydrazide and/or 3-amino-5-pyrazolone (1:1 molar ratio) to give novel series of 1,3-dipyrazole indole derivatives 3, 7, 9 and 11, respectively. On the other hand, Knoevenagel condensation of 1 with malononitrile gave ethyl 2-(3-(2, 2-dicyanovinyl)-1H-indol-1-yl) acetate (11). Reaction of 11 with 2-cyanoacetic acid hydrazide, 3-amino-5-pyrazolone, hydrazine hydrate, urea, thiourea and/or guanidine yielded 1, 6-diaminopyridine 12, pyrano(2,3-c)pyrazole 14, pyrazole 16 and pyrimidine derivatives 18a-c, respectively. Reaction of the latter compounds with 3-amino-5-pyrazolone furnished a novel series of 1, 3-diheterocycle indole derivatives 13, 15, 17 and 19a-c, respectively. Ten new target compounds 3, 6, 8, 10, 13, 15, 17 and 19a-c were tested for in vitro antiproliferative activity against A-549, MCF7, HCT-116 and HEPG2 cancer cell lines. In addition, molecular docking study of the most promising antiproliferative compounds against human DNA Topoisomerase I (PDB ID: 1T8I) theoretically is discussed.Results: Compounds 3, 6, 8 and 17 showed potent in vitro antiproliferative activity. Docking scores of the latter compounds were observed better than co-crystalline ligand.Conclusion: Further work is recommended to confirm the inhibition of TopoI in a specific bioassay
