Investigating Antibacterial Activities of Phytochemicals from Terminalia chebula and Terminalia bellirica fruit extract: An in vitro and in silico Study
Authors: M.K. Geetha Nambiar , Shameera Ahamed T.K.
Published: June 2024

This study aims to investigate the antibacterial activities of phytochemicals derived from Terminalia chebula (T. Chebula) and Terminalia bellirica (T. bellirica) through a combined approach of in vitro and in silico analyses. T. chebula and T. bellirica are medicinal plants widely recognized for their therapeutic properties and have been traditionally used to treat various infectious diseases. The potential antibacterial properties of these plants have drawn significant interest in recent years. In the in vitro phase of the study, crude extracts of dried fruit of T. chebula and T. bellirica are prepared and subjected to various antibacterial assays against a panel of clinically significant bacterial strains. It has been found that both extracts were effective against Staphylococcus aureus but had no inhibitory effect on Escherichia coli and Salmonella typhi at the tested concentrations. Furthermore, the study incorporated an in silico analysis to predict the interactions between the active phytochemical constituents and Staphylococcus aureus targets. Molecular docking was employed to examine the binding affinity and mode of interaction of these phytochemicals with the active site of protein DNA Gyrase of Staphylococcus aureus (3U2D). Most of the phytochemicals posed the highest binding affinity than inbuilt ligands. The protein interacted effectively with phytochemicals through various types of interactions including hydrogen bonding, electrostatic interactions, carbon-hydrogen bonding, metal-ion coordination and hydrophobic interactions. These interactions suggest potential binding mechanisms and provide important information about the potential biological activities of these phytochemicals. From ADME and toxicity analysis, phytochemicals "Syringic acid," "Ellagic acid" and "Punicalagin" from Terminalia chebula and "Ellagic acid," "Chebulagic acid" and "Terchebin" from Terminalia bellirica emerged as potential druggable candidates with relatively low toxicity concerns.

Published: June 2024

This study presents the dielectric characteristics of CaCu3Ti4O12. The X-ray diffraction analysis confirmed that the tested sample has a single-phase structure. The shape of the grains underwent significant variation with changes in sintering temperature. The actual permittivity undergoes an increase from 500 to 104 as the sintering temperature rises. The observed variations in dielectric characteristics of the samples (both in terms of real and imaginary components) can primarily be attributed to the presence of grains and grain boundaries.

Published: June 2024

Silicate solubilizing microbes (SSM) are crop beneficial microbes which facilitate silica uptake via plant roots by way of dissolving silicates and making it available in the form of monomeric silicic acid. Excessive use of synthetic fertilizers may negatively affect overall soil health and the environment. To ensure that crops provide competitive yields while preserving the ecological balance of the soil, it is necessary to develop and use bio-fertilizers. For this, a consortium is required which can solubilise complex form of phosphates, silicates etc. to provide important nutrients to crops while simultaneously maintaining the soil balance. In the present study, silicate producing microorganisms (Bacteria/Fungi) were isolated from different sites including water bodies and different soils. The samples were enriched with different agro-residues prior to isolation. Two different screening methods were used to select solubilising silicate bacteria (SSB) and solubilising silicate fungi (SSF). SSB producing the maximum zone of silicate dissolution were characterized and identified while SSF were selected on the basis of colour change in silica peptone broth. A total of four two bacteria (SSB) and two fungi (SSF) with potential of silicate solubilisation were isolated, screened, characterized and identified.

The control of the pathogenic agent vectors necessarily involves knowing their breeding sites. This study aimed to identify the breeding sites of mosquitoes inside and around the University of Korhogo (Ivory Coast). The methodological approach consisted to carry out larval surveys for three months (July, August, September) covering the rainy season. A total of 83 larval breeding sites were identified inside the university and 165 larval breeding sites in the peripheral areas. Inside, only puddles of water and cement mixers were identified as larval breeding sites of mosquitoes, puddles of water being the most productive. On the contrary, around the university, a multiplicity of larval breeding sites (bowls, tires, cans, buckets, cans, flowerpots, canaries, kettles and puddles) was identified. Puddles of water were the most encountered lodgings. On the other hand, tires and canaries were the most productive larval breeding sites respectively. All the collected larvae during the study period, belong to three genera of mosquitoes Aedes (Meigen, 1818), Culex (Linnaeus, 1758) and Anopheles (Meigen, 1818). Aedes was the most abundant in number of individuals. Inside the university, five species Aedes aegypti (Linnaeus, 1762), Culex quinquefasciatus (Say, 1823), Culex nebulosus (Theobald, 1901), Culex tigripes (de Grandpré & d'Emmerez de Charmoy, 1900) and Anopheles gambiae s.l. (Giles 1902) were identified. In the peripheral areas of university, eight species Aedes aegypti, Culex quinquefasciatus, Culex nebulosus, Culex tigripes, Culex decens (Theobald, 1901), Culex Cinereus (Theobald, 1901), Anopheles gambiae s.l. and Anopheles funestus (Giles, 1900) were identified. The findings are very relevant because they could be used in vector-borne disease control strategies in the event of an epidemic.

Cubane Pyrolysis: Scaling Bond Polarity with Universal Polynomials
Authors: Ayarde Henríquez Leandro , Guerra Cristian , Chamorro Eduardo
Published: June 2024

This work gauges an emerging methodical approach to elucidate an intimate multi-correlation between electron reorganizations, most stable molecular configurations, and the topographical description of relevant chemical processes through an indepth reevaluation of the chemical bonding analysis underpinning the cubane pyrolysis mechanism reported by Seif et al. [RSC Adv., 2020, 10, 32730-32739]. A fold-cusp unified model of universal functions for scaling bond polarity is derived from that multi-nexus. The scaling showed that values of the bond polarity index within the interval [0, 10-5] au correspond to the cusp unfolding, while the fold spans over a wider interval, [10-3, ∞) au. Contrary to previous observations, no cusp flag was detected upon re-examining single scissions and double formations/breakages of carbon-carbon bonds in the first step of the reaction mechanism (i.e., cubane → bicyclo[4.2.0]octa-2,4,7-triene), as demonstrated by the determinant of the Hessian matrix at all potentially degenerate critical points of the electron localization function along the intrinsic reaction coordinate. The transannular ring opening featuring the second elementary reaction, bicyclo[4.2.0]octa-2,4,7-triene → 1,3,5,7-cyclooctatetraene, is the only chemical process exhibiting cusp characteristics, underscoring the model’s reliability. The computed thermochemical dataset closely matches the experimental values, highlighting the robustness and accuracy of the derived insights.
The global threat from the irreversible accumulation of trifluoroacetic acid (TFA)
Authors: Arp Hans Peter H. , Gredelj Andrea , Glüge Juliane , Scheringer Martin , Cousins Ian T.
Published: June 2024

Trifluoroacetic acid (TFA) is a hydrophilic, non-degradable substance that has been increasing in concentrations within diverse environmental media, including rain, soils, human serum, plants, plant-based foods, and drinking water. Currently, TFA concentrations are orders of magnitude higher than those of other per- and polyfluoroalkyl substances (PFAS). This accumulation is due to many PFAS that have TFA as a transformation byproduct, including several fluorinated gases (F-gases), high-volume pesticides, pharmaceuticals and industrial chemicals, in addition to direct industrial release. Due to TFA’s extreme persistence and mobility, these concentrations are increasing irreversibly. What remains less clear is the thresholds where irreversible effects on local or global scales occur. There are indications from mammalian toxicity studies that TFA is toxic to reproduction and that it exhibits liver toxicity. Ecotoxicity data are scarce, with most data for aquatic systems; fewer data are available for terrestrial plants, where TFA bioaccumulates most readily. Collectively, these trends imply that TFA meets the criteria of a planetary boundary threat for novel entities because of increasing planetary-scale exposure, where potential, irreversible disruptive impacts on vital earth system processes could occur. The rational response to this is to instigate binding actions to reduce emissions of TFA and its many precursors.
Germanium Distributions in Zeolites Derived from Neural Network Potentials.
Authors: Saha Indranil , Erlebach Andreas , Nachtigall Petr , Heard Christopher J. , Grajciar Lukáš
Published: June 2024

Germanosilicate zeolites have played a pivotal role in the recent surge in synthesis of novel zeolite topologies. This success has been attributed to the combined effect of the high hydrolytic lability and specific distribution of germanium within the zeolitic framework, e.g., favoring the double four-ring (D4R) structural units. While experimental determination of germanium distributions remains limited, their in silico investigation has been hampered by the high computational cost of ab initio calculations. To overcome these limitations, we have developed neural network potentials (NNPs) that can efficiently explore a wide range of distributions in germanosilicate zeolites, while maintaining the accuracy of the ab initio (dispersion-corrected GGA DFT) training dataset. Through comprehensive screening of low-energy germanium distributions for five zeolite topologies (UTL, BEC, UOV, IWW and *CTH) across a broad range of Si/Ge ratios, we have identified a key factor governing the distribution of germanium in these D4R-containing zeolites, which is the tendency of germanium to cluster. The clustering initiates at the D4R units, leading to a preference to occupy these units at low to medium Ge loading (Si/Ge > 5). However, at high Ge loading, the Ge tends to phase separate into Ge-rich and Ge-poor regions, regardless of the specific structural unit. The zeolite topology was shown to be capable of modulating these trends in germanium distribution (e.g., UTL strongly favors D4R occupation even for low Si/Ge ratios), which suggests the possibility to develop design strategies for targeted zeolite synthesis. The NNPs presented herein enable rapid evaluation of these design strategies across a wide range of candidate zeolite structures and experimentally relevant Si/Ge ratios.
C(sp3) Cross-Couplings of Benzyl and Tertiary Halides with Thiols or Alcohols Catalyzed by Iron

Published: June 2024

Various metal catalysts have proven effective in carbon–heteroatom bond formation with softer heteroatomic nucleophiles, but examples remain largely limited to sp2 hybridized carbon electrophiles. Here, we report the coupling of sp3 hybridized benzyl or tertiary halides with soft thiol nucleophiles catalyzed by iron. The reaction is broad in substrate scope for both coupling partners and applicable in the construction of congested tri- and tetrasubstituted carbon-centers as well as beta-quaternary thioethers. The synthetic utility is further emphasized by the coupling of alcohol nucleophiles, gram-scale synthesis, thiol bioconjugation, and rapid herbicide library synthesis. Results from mechanistic experiments are consistent with a stereoablative pathway that likely involves a carbon radical intermediate. Overall, we provide an efficient method to prepare pharmaceutically and materially relevant carbon–sulfur and carbon–oxygen bonds by expanding iron-catalyzed cross-coupling reactions to the coupling of sp3 hybridized carbon electrophiles with soft nucleophiles.

Etherification and amination of aryl halide scaffolds are commonly used reactions in parallel medicinal chemistry to rapidly scan structure-activity relationships with abundant building blocks. Electrochemical methods for aryl etherification and amination demonstrate broad functional group tolerance and extended nucleophile scope compared to traditional methods. Nevertheless, there is a need for robust and scale-transferable workflows for electrochemical library synthesis. Herein we describe a platform for automated electrochemical synthesis of C-X arylation (X = NH, OH) libraries in flow. A comprehensive DOE identifies an optimal protocol which generates high yields across > 30 aryl halide scaffolds, diverse amines (including electron-deficient sulfonamides, sulfoximines, amides, and anilines) and alcohols (including serine residues within peptides). Reaction sequences are automated on commercially available equipment to generate libraries of anilines and aryl ethers. The unprecedented application of potentiostatic alternating polarity in flow is essential to avoid accumulating electrode passivation. Moreover, it enables reactions to be performed in air, without supporting electrolytes and with high reproducibility over consecutive runs. Our method represents a powerful means to rapidly generate nucleophile independent C-X arylation libraries using flow electrochemistry.

Spectroscopy is an integral part of chemical research, and the operation of any spectroscopic instrument is critical in chemical education. This study presents a low-cost, do-it-yourself (DIY) style spectrophotometer system that can be adapted for UV-Vis, fluorimetry, and atomic emission applications. The DIY system is constructed with commonly available hardware and 3D-printed parts, totaling less than $50. Python code is also provided to process the color spectrum image into intensity vs. wavelength data, similar to any commercial-level instrument. The functionality of the DIY spectrometer is demonstrated with the absorption of KMnO₄, fluorescence of fluorescein, and atomic emission of LiCl, NaCl, BaCl₂, and SrCl₂. All the collected spectra show accurate results compared to a commercial instrument or existing literature. The goal of this project is to provide a hands-on platform for undergraduate students to see and modify the individual components of a spectrophotometer, which will enhance their understanding of the underlying principles.
A computational study of possible mechanisms of singlet oxygen generation in miniSOG photoactive protein
Authors: Giudetti Goran , Blinova Anastasia R. , Grigorenko Bella L. , Krylov Anna I.
Published: June 2024

We report high-level electronic structure calculations of electronic states in the miniSOG (for mini Singlet Oxygen Generator) photoactive protein designed to produce singlet oxygen upon light exposure. We consider a model system with a riboflavin (RF) chromophore. To better understand the photosensitization process, we compute relevant electronic states of the combined oxygen-chromophore system and their couplings. The calculations suggest that singlet oxygen can be produced both by inter-system crossing, via a triplet state of the RF(T1)×O2(3Σ− g ) character as well as by triplet excitation energy transfer via a singlet state of the same character. The calculations also suggest a pathway for the production of the triplet state of the chromophore via internal conversion facilitated by oxygen. Our results provide concrete support to previously hypothesized scenarios.
A PRELIMINARY STUDY OF LI LIUFANG'S VIEW OF CALLIGRAPHY AND HIS RELATIONSHIP WITH DONG QICHANG
Authors: Jiang Xin
Published: June 2024

Li Liufang was an influential artist in the art scene of the late Ming Dynasty in Jiading. He excelled in poetry, calligraphy, and painting. Gui Youguang’s “theory of nature and spirit” had a significant impact on his view of calligraphy. He advocated “Learn the virtues of the ancients” and “Writing one’s own thoughts”. Dong Qichang was the most prominent artist of the late Ming Dynasty in Songjiang. Because of Songjiang’s proximity to Jiading and the relationship between the two, Li Liufang is often seen as a follower of Dong Qichang when many scholars study the history of the acceptance of Dong qichang’s art. However, this is incorrect. The interaction between Li Liufang and Dong Qichang was minimal, and their styles of painting and calligraphy differed significantly. Both Dong and Li’s academic roots can be traced back to the Tang-Song school of literature and art in the late Ming Dynasty. Thus, there are similarities between Dong and Li’s literary and artistic philosophies. Dong Qichang received the inheritance from Tang Shunzhi, which is similar to the “theory of nature and spirit”. In other words, these two men received their literary ideas from the same school of inheritance, and there is no mutual imitation between the two.
Flora of Singapore precursors, 41: Taxonomic updates on the moss genus Ectropothecium and allied genera (Hypnaceae)
Authors: He S. , Ho B.-C.
Published: June 2024

Eight species of Ectropothecium Mitt. previously reported and misapplied in Singapore have been critically investigated, which resulted in different reinterpretations and taxonomic reshufflings of several taxa, and discovery of new records for Singapore. Two native species, Ectropothecium monumentorum (Duby) A.Jaeger and E. tutuilum (Sull.) Mitt. (with E. ichnotocladum (Müll.Hal.) A.Jaeger and E. moritzii A.Jaeger as newly proposed synonyms) remain recognised in the genus. Ectropothecium stigmophyllum Broth. is a non-native species newly recorded in Singapore. Ectropothecium singapurense Dixon is transferred to Calohypnum Sakurai as C. singapurense (Dixon) S.He & B.C.Ho, and continues to be treated as a species endemic to Singapore. Ectropothecium buitenzorgi auct. non (Bél.) Mitt. and E. incubans auct. non (Reinw. & Hornsch.) A.Jaeger were misapplied names for the native Neoptychophyllum dixonii (M.Fleisch.) S.He & B.C.Ho. Crepidophyllum modestum Herzog (reported for the first time with sporophytes for the genus) is a non-native record new to the country. Calohypnum, Crepidophyllum Herzog and Neoptychophyllum S.He represent new generic names for Singapore. Ectropothecium intorquatum (Dozy & Molk.) A.Jaeger and E. zollingeri (Müll.Hal.) A.Jaeger are excluded from Singapore. Additionally, Ectropothecium sodale (Sull.) Mitt. was found only in cultivation; thus, it is not treated in the flora. Lectotypes are designated for Ectropothecium moritzii A.Jaeger, E. moritzii var. stereodontoides Dixon, Hypnum ichnotocladum Müll.Hal., and Hypnum monumentorum Duby. New combinations are proposed in Calohypnum and Neoptychophyllum.

Territorializar las memorias, abrazar los mundos.
Authors: Bidaseca Karina
Published: June 2024

Este artículo constituye una exploración acerca del pensamiento situado y del afrocentrismo en la obra de la artista cubana de color Ana Mendieta. Aborda las prácticas de éstetesis femeninas transatlánticas, tomando la obra de la artista en Oaxaca, México y en Cuba, para abrazar los conceptos organizadores de “territorios de la memoria”, “arte feminista situado y descolonial”.  Asimismo, se toman esos momentos de la obra de la artista entre los años 1977 a 1982 que nos permitan desarrollar el concepto de “poética (erótica) de la Relación”, acuñado por mí en la inspiración del cruce de obra de Édouard Glissant y Audre Lorde, como propia de la territorialización de la memoria. A nivel metodológico, se basa en una combinación de técnicas de revisión bibliográfica y documental, y trabajo de archivo etnográfico con metodología socioafectiva plasmada en la amistad entre mujeres.

O trabalho investiga o contexto que levou a Acadêmicos do Grande Rio, escola de samba do Grupo Especial do Rio de Janeiro, a participar do evento Carnaval Virtual – Edição Especial, em fevereiro de 2021. Primeiramente, em cotejo com notícias que mobilizaram o “mundo do samba”, serão descritas atividades realizadas pelas agremiações sambistas no decorrer de 2020, quando oavanço da pandemia de covid-19 tornava impossível qualquer previsão sobre os festejos carnavalescos de 2021. Depois, as lentes enfocarão o universo do carnaval virtual, com base nas teorizações de autores como Pierre Lévy. Num terceiro momento, será analisada a participação da Grande Rio nos desfiles da liga Carnaval Virtual: a “reapresentação” do enredo Tata Londirá: o Canto do Caboclo no Quilombo de Caxias em um contexto festivo muito diferente daquele observado na Marquês de Sapucaí é um experimento de cujas janelas brotam questões sobre hibridismo, virtualização e cibercultura.

Foram selecionadas para este ensaio fotografias que interpretamum espaço em específico do barracão da escola de samba de Duque de Caxias: a “sala das placas”, espaço onde se dava a produção seriada de “placas de vacuum forming” (com a utilização de materiais como folhas de acetato e borracha EVA) e o acúmulo das “formas” (esculturas em resina) utilizadas em anos anteriores – ou seja, um espaço de produção em escala fabril e um espaço de memória. O breve estudo se propõe a lançar centelhas reflexivas acerca da possível leitura da “sala das placas” do barracão da Grande Rio, informalmente conhecida como “sala do Seu Tonico”, enquanto lugar que dialoga com a visão de uma “sala dos milagres” do catolicismo popular brasileiro, com o acúmulo de ex-votos.
Identidade e Risco
Authors: Vasconcelos Bruno
Published: June 2024

O ensaio a seguir pretende discutir o importante conceito de identidade, central no pensamento sociológico, e também marcador fronteiriço com as demais áreas de humanidades. Mais especificamente, trata-se de pensar a relação entre os processos identificatórios e a noção de risco, fundamental para a compreensão da realidade social contemporânea. O ensaio se desdobra criticamente, pontuando relações dialógicas tanto na interpretação da teoria sociológica sobre a identidade quanto sobre a noção de risco. Num primeiro momento, os conceitos serão mediados pela discussão que desdobra a relação entre identificação, conhecimento e construção social da realidade, para, posteriormente, aprofundar a interpretação pensando a redefinição/reestruturação dos sentidos da modernidade e dos próprios processos identificatórios. Finalmente, o ensaio pretende indicar uma nova via de compreensão da ideia de risco, imaginando possibilidades de reinterpretação do fenômeno da identificação; costura entre agência, estrutura e angústia.

Authors: Menendez Larissa , Amorim Oliveira Ana Caroline , Dias Jose´
Published: June 2024

Este artigo tem como objetivo refletir sobre as possibilidades de aplicação da lei no 11.645/2008, que trata da obrigatoriedade dos conteúdos da história da África e dos povos africanos e da história dos povos indígenas nos currículos da Educação Básica, a partir de um relato de experiência de uma oficina no âmbito do Programa Nacional de Cooperação Acadêmica na Amazônia - PROCAD. Tal atividade se desenvolveu com estudantes de licenciatura e professores da Educação Básica em caráter virtual devido à pandemia da Covid-19. Essa oficina proporcionou um debate sobre arte, etnologia e educação nos currículos escolares a partir de uma abordagem histórica, sociológica e antropológica, tensionando os conteúdos postos na Educação Básica. Assim, o interesse identificado pelos professores participantes e pelos licenciandos, bem como a demanda por outras atividades como esta demonstra a necessidade de maior visibilidade da referida lei.
Procissão de São Raimundo dos Mulundus:
Authors: De Almeida Brasil Marcus Ramusyo
Published: June 2024

A fé é o que alimenta as fotografias realizadas por Marcus Ramusyo de Almeida Brasil durante a Procissão do Festejo de São Raimundo do Mulundus, em 22 de agosto de 2012. A procissão perfaz um caminho de 7 quilômetros da cidade de Vargem Grande – MA, até o povoado de Paulica, onde é rezada uma missa e são realizadas diversas atividades de socialização, quando então os romeiros retornam à paróquia da cidade de Vargem Grande. A figura do vaqueiro montado a cavalo, com suas vestes de couro, que segue em procissão com outros tantos, revela o aspecto cultural da fé. A presença de jovens, velhos e crianças reforça a continuidade desta manifestação, que tal como tantas outras da cultura maranhense, mostra-se em toda sua vitalidade a partir do reencenar constante das tradições, e, nas tradições, as práticas que delas emergem. Tradições estas que longe de pertencerem ao passado, indagam o futuro a partir das vivências e experiências que transformam o presente. O festejo começa às 05 horas da manhã com o toque da alvorada, conduzida pela Dona Nini, guardiã das liturgias da procissão de São Raimundo Nonato dos Mulundus, realizada no dia 22 de agosto de cada ano, na cidade de Vargem Grande, Maranhão, Brasil. Devotos, romeiros e vaqueiros a cavalo já esperam a hora de iniciar a procissão. Pessoas peregrinam de todas as partes do Maranhão e de outros estados do Brasil para prestar devoção, fazer e pagar promessas ao santo popular, adotado e sincretizado pela igreja católica. Nos dias 30 e 31 de agosto acontece o encerramento da festa, com o seu desenrolar mais profano. A história de São Raimundo Nonato dos Mulundus está envolta em narrativas de mistério, fé e devoção, no contexto das crenças populares e das práticas performáticas socioculturais que as engendram. Raimundo Nonato Soares Cangaçu nasceu em 31 de outubro de 1700, no povoado de Vargem Grande. Veio a falecer no dia 31 de agosto de 1732. Revela a memória coletiva que o vaqueiro Raimundo Nonato estava cavalgando em velocidade pelas matas quando bateu com seu cavalo em uma árvore. Tanto ele quanto seu cavalo ficaram combalidos, ali pereceram e morreram. No entanto, ao entrar em estado de decomposição, em vez de feder e ser comido pelos vermes, o corpo de Raimundo Nonato se santificara, emanava, então, perfume de flores. Nasceu, ali, linda vegetação. O local de sua morte tornou-se lugar de peregrinação com o passar do tempo. Seu nome se manteve forte no imaginário popular do sertanejo da região, vindo a se tornar o santo protetor dos vaqueiros e daqueles que vivem nos rincões do Maranhão profundo, através de quase 300 anos de tradição.

Published: June 2024

Neste ensaio fotográfico acompanhamos o ciclo carnavalesco das escolas de samba de Manaus (AM) iniciado na conturbada apuração do carnaval de 2014, que terminou com todas as escolas declaradas campeãs, até o desfile do carnaval de 2015. Neste caminho buscamos ressaltar as particularidades das escolas de samba na cidade e acompanhar as redes de sociabilidade produzidas por seus componentes. A pesquisa organiza-se em três momentos, sendo o primeiro a abordagem das estratégias de identificação frente à cidade por parte de uma escola de samba em um bairro estigmatizado. Logo após, enfocamos o processo de reafirmação simbólica da escola de samba em um bairro socialmente valorizado. Finalmente chegamos ao desfile como momento apoteótico das agremiações.

Authors: Ghani Hafiz Abdul , Ahmad Hafiz Saeed
Published: June 2024

From Aristotle’s Nicomachean Ethics to modern psychologists such as Martin Seligman (b.1942), it has been an old-age human quest to know the principles of success, happiness, and fulfillment. In the rapidly changing modern world, defining the concept of a ‘successful and happy life’ through the teachings of various philosophies has become an important and popular study. A great number of self-help books and research articles are being published to teach the principles and practices of success. Different ideologies and philosophers suggest different principles of success. Some of which may be effective while some may not be. It is important to explore the most authentic and reliable principles of success. For this article, the literature review of the Qur’ānic verses has been conducted under a governing question: What is true success, and how to attain it in the light of Qur’ān? The goal of this study is to identify the Qur’ānic view and principles of success and examine their validation for immediate socioeconomic success as well as the ultimate bliss. This article has attempted to define the concept of true success, explore the best pathway to success, and elaborate on the essential principles of fulfillment in the light of Islam. The researchers have used the qualitative method to analyze Qur’ānic verses with deductive reasoning as their research methodology.
