Computational Study of C−H/C−C Activation and Functionalization with Nitrene, Carbene and Related Complexes
Authors:   , Sun Zhicheng
Published: February 2025

This dissertation involves inorganic/organometallic catalysis models, in particular the functionalization of carbon-hydrogen and carbon-carbon bonds. Computational methods have been utilized to better understand the factors affecting the kinetics and thermodynamics of C−H and C−C bond activation/functionalization in this dissertation. Chapter 2 investigates methane C−H activation with a diiminopyridine nitride/nitridyl complex of 3d transition metals and main group elements via three competing pathways: 1,2-addition/[2 + 2] addition, insertion and H-atom abstraction/proton coupled electron transfer. Chapter 3 investigates a transition metal catalyzed C=C bond functionalization involving C−N bond formations to synthesize aziridines from aromatic and aliphatic alkenes. The study focuses on anionic 3d transition metal (M = Mn, Fe, Co and Ni) triphenylamide-amine complexes with nitrene active intermediates for the aziridination reactions. Chapter 4 investigates a disphenoidal Ni(II) azido complex participating in intramolecular C−H functionalization and amination via a putative Ni nitridyl intermediate and a 1,2-addition/[2 + 2] addition pathway. In Chapter 5, methane oxidative addition to the Cp*ML (Cp* = η5-C5Me5; M = Co, Rh, Ir , L = CO, PMe3) motif is compared and contrasted when the classic CO and PMe3 ligands are replaced with the cyclic alkyl(amino) carbene (CAAC) as ancillary ligands.
Queer in Fandom: A Uses and Gratifications Analysis of the Katy Perry Fan Community on Twitter
Authors:   , Poteet Maddison Jade
Published: February 2025

Online fandom communities exist as a hub of subcultural construction for people across the globe. For queer people, fandom represents a space to safely converge over mutual interests. Previous research has focused on queer fans and popular music fans independently, often taking a pathological approach. This study qualitatively examines queer participants in the Katy Perry fandom through surveys and one-on-one interviews. The theoretical backbone of the study is built around uses and gratifications theory, seeking to understand motivations for fandom participation. The concepts of the heteronormative matrix and queer resistance are additionally incorporated to analyze how LGBTQ+ fans combat societal norms. This research found seven motivations for queer fans to participate in online fandom, providing insight into an understudied community.
Participation in the Play of Nature: A Hermeneutic Approach to Environmental Aesthetics
Authors:   , Aloi Michael Joseph
Published: February 2025

Within the environmental aesthetics literature, there is a noticeable schism between two general approaches to understanding the aesthetic value of nature: the ambient approach and the narrative approach. Ambient thinkers focus on the character of aesthetic appreciation of nature, the way in which one is embedded in multi-sensory environment. These ambient theorists emphasize the importance of those aesthetic experiences that are difficult to articulate. Narrative thinkers argue that aesthetic appreciation of nature is enhanced and enriched by narratives that are relevant to the natural object or environment encountered. Certain narratives – usually those based on scientific knowledge – encourage a depth of appreciation that is inaccessible to those unfamiliar with the narratives. In this dissertation, I attempt to articulate an account of environmental aesthetic experience that does justice to both of these approaches by drawing on the resources of philosophical hermeneutics, and especially on the aesthetic theory of Hans-Georg Gadamer. The most important aspects of Gadamer's work for environmental aesthetics are his phenomenology of play, his revival of practical philosophy, and his emphasis on the interpretive character of all understanding. His discussion of play fleshes out the core of ambient accounts, his focus on interpretation explains the insights of narrative accounts, and the two accounts are tied together by his attention to practice.
The Impacts of Urban Sustainability on Economic Prosperity: Sustainability in the Spotlight
Authors:   , Cooksey Christy
Published: February 2025

City officials are in the position to adopt and implement policies within their jurisdiction that can have lasting impacts for businesses, people, and the environment. Sustainability research has highlighted the need to protect the environment by adopting policies which support the three E's of sustainable development (environment, equity, and economy). Stepping aside from the traditional mechanisms for building a successful city focused on economy first can be challenging for policy makers. The problem city officials face is that changes towards environmental protectionism have long been considered harder on city economy than traditional development focused on economic prosperity. Additionally, sustainability planning is thought to mitigate potential negative impacts that planning for environmental protectionism and social equity may have on economic prosperity. To examine this problem faced by city officials, ordinal regression analyses was used to analyze (1) the possible effects of environmental protectionism and social equity on a city's economic prosperity, and (2) whether sustainability planning has a moderating affect between environmental protectionism, social equity, and economic prosperity. This analysis demonstrates that environmental protectionism and social equity are not associated with a decline in economic prosperity. Sustainability planning was directly associated with increased economic prosperity but did not moderate the relationship between environmental protectionism and economic prosperity.
This Land is My Land: The Dynamic Relationship between Migration and the Far-Right
Authors:   , Winn Meredith
Published: February 2025

This dissertation examines the dynamic intersections of the relationship between migration and the far-right through three empirical, stand-alone chapters. The first substantive chapter re-evaluates existing theories of far-right support using a novel theory and comprehensive dataset to assess how immigration opinion and immigration levels interact to shape individual far-right support. The findings suggest that increases in asylum-based migration are associated with increased far-right voting, but that this is effect is mainly observed in those with negative or neutral opinions toward immigration. The second substantive chapter examines the other side of this relationship by analyzing the impact of far-right electoral and legislative success on asylum-recognition rates in EU member states. The results of empirical analyses show that when far-right parties gain legislative seats, the expected rate of asylum approvals decreases. This suggests that far-right parties in legislatures have measurable effects on migration outcomes. Finally, the third substantive chapter uses original field research to assess how far-right politics impacts the lived experiences of immigrants in France and Switzerland, relying on a small survey and interviews conducted in the field. The results show that immigrants are generally aware of far-right parties and distrustful toward them. However, undocumented migrants and asylees are among the most negatively impacted by far-right activity. Overall, this dissertation moves beyond the entrenched debate of how migration does or does not facilitate far-right support and contributes to the academic understanding of how migration and far-right politics interact.
The Relationship between Instructional Coaches and Principals
Authors:   , Norman Lani Suzanne
Published: February 2025

As a form of teacher professional development, districts and schools are turning to an instructional coaching model for teacher learning, growth, and support. To date, however, few have sought to identify the specific characteristics and conditions that contribute to the success of the instructional coach, particularly in terms of the principal and instructional coach relationship. The purpose of this study was to explore the perceptions of instructional coaches regarding the types of supports, conditions, and relationships they encounter and believe they need in their work with principals to more effectively impact teacher instruction, thus, student achievement. An exploratory case study research design and approach was utilized. Two different data collection tools were used to interview instructional coaches: focus group interviews and semi-structured, face-to-face individual interviews. The following principal behaviors that impact the instructional coaches' work the most were identified: (a) time for the coach and principal to meet, (b) trust and mutual respect built from the principal and coach relationship, (c) protection of the coaching role from administrative duties, (d) a public endorsement of the coaches' work and impact, (e) shared vision and leadership, and (f) a culture of growth and continued learning. Specific principal actions, practices, and critical components of the instructional coach and principal relationship that impact instructional coaches' work with teachers, implications for future practice, and recommendations for future research are provided.
Evaluating Variables that Influence Research Staff Performance
Authors:   , Rodriguez Ana
Published: February 2025

Performance analysis, based on operant analysis of behavior, has been utilized since the 1960s to investigate behavioral skills or deficits in the workplace. One type of analytical tool is Carr et al.'s Performance Diagnostic Checklist- Human Services (PDC-HS). This functional assessment allows investigators to pinpoint causes of performance issues (e.g., a training issue, task clarification/prompting, insufficient resources/materials/processes, or performance consequences/effort/competition). Typically, the PDC-HS is used with clinicians and therapists. The purpose of this study is to extend Carr et al. by evaluating the PDC-HS in assessing the clinical performance of graduate-level research assistants working at a specialized clinic for the assessment and treatment of severe behavior disorders. For each participant, three supervisors, the study investigator and the participants themselves completed the PDC-HS with respect to the performance concern. Results of the PDCH-HS showed variability in congruence across the three groups of respondents. Due to the occurrence of the global coronavirus disease 2019 (COVID-19) pandemic during the study's investigation, the project was modified to assess different clinical performance involving safety procedures. The PDC-HS was re-administered to assess participants' cleanliness behavior and a subsequent targeted intervention was designed. Results showed no improvement of performance for 4/4 participants in the nontargeted intervention for clinic session performance and an increase for 1 participant in the targeted intervention for the cleanliness performance. Implications of PDC-HS results and limitations are discussed.
Analysis of the Cytochrome P450 and UDP-Glucuronosyltransferase Families and Vitamin D3- Supplementation in Anoxia Survival in Caenorhabditis elegans
Authors:   , Agarwal Sujata
Published: February 2025

Alteration in diet and knockdown of detoxification genes impacts the response of C. elegans to oxygen deprivation stress. I hypothesized that feeding worms a vitamin D3-supplementation diet would result in differential oxygen deprivation stress response. We used a combination of wet lab and transcriptomics approach to investigate the effect of a vitamin-D3 supplemented diet on the global gene expression changes and the anoxia response phenotype of C. elegans (Chapter 2). C. elegans genome consists of 143 detoxification genes (cyp and ugt). The presence of a significant number of genes in these detoxification families was a challenge with identifying and selecting specific cyp and ugt genes for detailed analysis. Our goal was to understand the evolution, phylogenetic, and expression of the detoxification enzymes CYPs and UGTs in C. elegans (Chapter 3). We undertook a phylogenetic and bioinformatics approach to analyze the C. elegans, detoxification family. Phylogenetic analysis provided insight into the association of the human and C. elegans xenobiotic/endobiotic detoxification system. Protein coding genes in C. elegans have been predicted to be human orthologs. The results of this work demonstrate the role of C. elegans in the identification and characterization of vitamin D3 induced alterations in gene expression profile and anoxia response phenotypes and the identification of human orthologs for the detoxification enzymes and provides insight into the gene expression pattern.
Bohuslav Martinů's Oboe Concerto, H. 353: A New Piano Reduction of the Orchestral Score
Authors:   , Jeoung Ko Eun
Published: February 2025

Bohuslav Martinů's "Concerto for Oboe and Small Orchestra" is one of the most frequently played pieces in the oboe repertoire. For this reason, it is often played with the piano reduction instead of the orchestra in oboe recitals. However, the existing piano reductions include many errors and discrepancies from the orchestral score, misrepresent the orchestration, sometimes fail to make the oboe entries clear, and tend to be unplayable for pianists. Moreover, the scores were published after the composer's death without him supervising the final editing. I have prepared a new, playable piano reduction to represent the orchestration more faithfully and help pianists work with their soloists more easily. Based on the work of Martin Katz, a prominent collaborative-pianist, I establish four principles for creating a new piano reduction. After scrutiny of the deficiencies of existing piano reductions, I suggest solutions for making the passages in question practical and bringing out the leading voices clearly so that the soloist can join in as easily as playing with an orchestra. To aid in reflecting the orchestral texture that Martinů created, I include abbreviated instrument names in many passages to help pianists to understand how to create balance. I have changed some passages completely to make the sound closer to the orchestral texture. All changes and suggestions are based on the orchestral score and its layout. This simplified and practical piano reduction should help pianists have more enjoyable and more successful collaborations with their soloists.
Identification and Characterization of a Mutation Causing Stunted Growth in Arabidopsis that is Linked to Phosphate Perception
Authors:   , Shaikh Mearaj Ahmed A J
Published: February 2025

Plant yield is an agronomic trait dependent on the transport of photosynthate from mature source leaves to sink tissues. Manipulating phloem transport may lead to increased yield, however in a previous study, Arabidopsis thaliana overexpressing sucrose transporter AtSUC2 in the phloem resulted in stunted growth and an apparent P-deficiency. In the course of further characterizing the phenotype and identifying the causative mutation, this research included 1) reverse genetics to test genes hypothesized to modulate carbon-phosphate interactions; 2) whole genome sequencing to identify all T-DNA insertions in plants displaying the phenotype; 3) genetic crosses and segregation analysis to isolate the causative mutation; and 4) transcriptomics to capture gene-expression profiles in plants displaying the phenotype. These phenotypes were traced to a T-DNA insertion located on chromosome 4. Transcriptomics by RNA-Seq and data analysis through bioinformatics pipelines suggest disruptions in metabolic and transport pathways that include phosphate, but do not support a direct role of well-established phosphate acquisition mechanisms. Gene At1G78690 is immediately downstream of the T-DNA insertion site and shows modestly increased expression relative to wild type plants. At1G78690 encodes O-acyl transferase, which is involved in processing N-acylphosphotidyl ethanolamine (NAPE) to N-acyl ethanolamine (NAE). Exogenous NAE application causes stunted growth in specific conditions. From the experiments described herein, At1G78690 emerges as the strongest candidate for causing the observed phenotypes.
A Mixed-Method Sequential Explanatory Study of Fundamental Motor Skills Competence of Underserved Preschool Children
Authors:   , Lee Joon Young
Published: February 2025

This dissertation investigated the roles of early childhood fundamental motor skills (FMS) competence on physical, cognitive, and psychosocial health outcomes among underserved preschoolers in Head Start, and examined parental influence on their children's FMS competence. An explanatory sequential mixed methodology was used to examine the predictive strength of FMS competence on physical, cognitive, and psychosocial health outcomes among 216 underserved preschoolers from six Head Start centers (Mage = 4.32, SD = 0.63; girls 56.5%). This methodology allowed for a follow-up qualitative aspect to explore the influence of parents' perceptions and behaviors on their child's FMS competence and health outcomes in a subsample of eight parent–child dyads who demonstrate high or low FMS competence in the quantitative data. The results of this dissertation suggest that preschoolers' FMS competence, especially locomotor skills, were associated with and predicted various health outcomes in sedentary behavior (β = -0.21), light physical activity (β = 0.23), executive function (β = -0.21), and perceived motor competence (β = 0.34). No significant influences of FMS competence on moderate-to-vigorous, body fatness, HRQoL were found (p > 0.05). We also found that positive parental influences (role modeling, support, and facilitation) were observed more often among preschoolers in the high FMS competence group. In addition, preschoolers with single, divorced, or young parents (age range 18–24) tended to show low FMS competence. The analysis of children's drawing pictures also indicated differences in images related to the moments when they played games or sports with parents based on their FMS competence levels. Practical implications and future research direction are discussed.

Jointly Making Inventory Stocking and Assortment Offering Decisions

Making the product assortment offer decisions for a customer requires keeping a balance between offering an assortment that will satisfy the current customer and reserving the products with scarce inventories for the customers who will arrive in the future. Therefore, whereas the assortment offer decisions should depend on the current inventories of the products, the stocking decisions should anticipate how the offered assortments will deplete the inventories, thereby creating a natural interaction between inventory stocking and assortment offer decisions. In “Coordinated Inventory Stocking and Assortment Customization,” Bai, El Housni, Rusmevichientong, and Topaloglu develop models that jointly make the assortment offer and inventory stocking decisions. Their models allocate the limited stocking capacity to the inventories for different products, while taking into consideration the assortment offer decisions that will be made for the customers arriving over a selling horizon.

Mercury waste pollution is an environmental health issue resulting from poor management of mineral production waste materials. Small-scale gold mining areas using amalgamation techniques still contribute high levels of mercury waste to the environment. The technical issue of inadequate storage of production waste materials warrants adaptive control studies for small-scale gold miners (PESK). The aim of this research is to determine the efficiency of chemical and biological mercury waste control in small-scale gold mining cases. This research is a literature review using the systematic review method. The obtained articles underwent review, analysis, and comparison of the systematic capabilities of chemical and biological control. The results of this research found 11 relevant study articles published between 2017-2024. Chemical and biological control methods are capable of reducing mercury levels in tailing water by up to 99%. The form of adaptive control for small-scale gold mining conditions is assessed pragmatically and based on reduced mercury levels. The conclusion of this research is that applied research on mercury waste pollution cases in small-scale mining is still relatively lacking. Efficiency in controlling mercury levels is more realistic using biological control. Laboratory test result approaches can indicate the potential of biological control with bioremediation techniques as an efficient adaptive control effort for small-scale gold miners.

Published: February 2025

The transdisciplinary approach to project-based learning is very interesting to study. Collaboration between several sciences produces integrated scientific products that will improve students' ability to solve a problem based on collaboration of scientific perspectives. Vocational schools that have a vision to produce competent and skilled experts in their fields must provide a foundation of other sciences in order to create quality human resources. This study attempts to collaborate several sciences (transdisciplinary) through project-based learning with the team-teaching method. This study also describes the stages in a case study of the transdisciplinary approach at one of the vocational schools with an excellent program (SMK center of excellence) in Sidoarjo Regency, Indonesia. This type of research is included in descriptive qualitative research with a case study approach. There are several problems in implementing the transdisciplinary approach to the student business center (SBC) program, namely: lack of time to collaborate, group dynamics played by some teachers are less effective, overlapping roles and inadequate funding. However, through the formation of teams in the classroom in a balanced manner, students can learn tolerance with peers, learn leadership skills and collaboration between teams. In addition, through a transdisciplinary approach, students will learn about the democracy of the learning environment by valuing their voices and teachers who empower them as students. The results of the evaluation related to the student business center (SBC) program through the distribution of questionnaires to students with 19 learning response indicators showed a figure of 65% or in the good category.

Authors: Amsidi Mukmin , Andriyani Andriyani
Published: February 2025

Entrepreneurship is the answer to the challenge of the need for creativity and innovation in solving problems or creating new opportunities, as applied in vocational-based curricula. Various vocational competencies and skills are trained to equip and prepare students to enter the dynamic world of work so that students can solve problems encountered around them through creative problem-solving. Therefore, in its teaching, real problem-solving exercises are needed with the help of learning media that can illustrate these real problems in detail with very realistic visuals. Thus, this study aims to develop a valid, practical, and effective animated film to visualize realistic problems of entrepreneurial practice to improve students' creative thinking skills. The research and development model used in this research is the descriptive ADDIE model, which shows systematic steps to produce an animated film with an entrepreneurship theme. The basis for selecting this development model is related to the special characteristics of the ADDIE model, namely developing products to relate the gap between educational research and educational practice, as well as emphasizing specific problems related to practical problems in teaching through applied research. Animated films with the theme of entrepreneurial practices can meet the criteria for product development feasibility in terms of validity, practicality, and effectiveness. The animated film media used has also proven to be a solution to the problems of students who have not been trained to think creatively in solving entrepreneurial practice problems so that students are more enthusiastic about learning and have meaningful learning experiences.

Aims

This study aimed to investigate whether the use of CT-based navigation enhances: 1) the accuracy of cup placement; and 2) the achievement rate of required range of motion (ROM). Additionally, we investigated the impact of using a large femoral head and dual-mobility liner on the achievement rates.

Methods

This retrospective study analyzed 60 manual and 51 CT-based navigated primary total hip arthroplasties performed at a single facility. Postoperative CT scans and CT-based simulation software were employed to measure the cup orientation and to simulate the ROM. We compared the absolute errors for radiological inclination (RI) and radiological anteversion (RA) between the two groups. We also examined whether the simulated ROM met the required ROM criteria, defined as flexion > 110°, internal rotation > 30°, extension > 30°, and external rotation > 30°. Furthermore, we performed simulations with 36 mm femoral head and dual-mobility liner.

Results

The absolute errors of RI and RA from the preoperative plan were significantly smaller in the CT-based navigation group (3.7° (SD 3.5°) vs 5.1° (SD 3.5°); p = 0.022, and 3.9° (SD 3.5°) vs 6.8° (SD 5.0°); p = 0.001, respectively). The proportion of cases achieving the required ROM in all directions was significantly higher in the CT-based navigation group (42% vs 63%; p = 0.036). The achievement rates of the required ROM were significantly higher with the use of a 36 mm ball or dual-mobility liner compared to the use of a 32 mm ball (65% vs 51%; p = 0.040 and 77% vs 51%; p ≤ 0.001, respectively).

Conclusion

CT-based navigation enhanced required ROM achievement rates by > 20%, regardless of the ball diameter. The improved accuracy of cup placement through CT-based navigation likely contributed to the enhancement. Furthermore, the use of large femoral heads and dual-mobility liners also improved the required ROM achievement rates. In cases with a high risk of dislocation, use of these devices is preferred.

Published: February 2025

As the number of IoT devices and the volume of data increase, distributed computing systems have become the primary deployment solution for large-scale Internet of Things (IoT) environments. Federated learning (FL) is a collaborative machine learning framework that allows for model training using data from all participants while protecting their privacy. However, traditional FL suffers from low computational and communication efficiency in large-scale hierarchical cloud-edge collaborative IoT systems. Additionally, due to heterogeneity issues, not all IoT devices necessarily benefit from the global model of traditional FL, but instead require the maintenance of personalized levels in the global training process. Therefore we extend FL into a horizontal peer-to-peer (P2P) structure and introduce our P2PFL framework: efficient peer-to-peer federated learning for users (EPFLU). EPFLU transitions the paradigms from vertical FL to a horizontal P2P structure from the user perspective and incorporates personalized enhancement techniques using private information. Through horizontal consensus information aggregation and private information supplementation, EPFLU solves the weakness of traditional FL that dilutes the characteristics of individual client data and leads to model deviation. This structural transformation also significantly alleviates the original communication issues. Additionally, EPFLU has a customized simulation evaluation framework, and uses the EUA dataset containing real-world edge server distribution, making it more suitable for real-world large-scale IoT. Within this framework, we design two extreme data distribution scenarios and conduct detailed experiments of EPFLU and selected baselines on the MNIST and CIFAR-10 datasets. The results demonstrate that the robust and adaptive EPFLU framework can consistently converge to optimal performance even under challenging data distribution scenarios. Compared with the traditional FL and selected P2PFL methods, EPFLU achieves communication time improvements of 39% and 16% respectively.

Abstract. Tat TQ, Khanh ND, Thi QVC. 2024. Characterization and identification of potential cellulolytic bacteria for bio-degradation of durian shell waste in Mekong Delta, Vietnam. Biodiversitas 25: 4284-4291. Microorganisms play crucial roles in the decomposition of plant biomass. This study aimed to isolate, screen, and identify potential mesophilic cellulose-degrading bacterial (CDB) strains from natural compost from durian shells (DS). Results revealed that a total of fifteen aerobic strains were isolated at 37°C, thirteen of which exhibited enzymatic degradation of cellulose, with cellulolytic index (CI) values ranging from 0.34 to 3.22. Five strains with CI values greater than 2.0 presented potential extracellular cellulase enzyme activity, with carboxymethyl cellulase (CMCase) at 0.18-0.31 U/mL and filter paper cellulase (FPase) at 0.03-0.19 U/mL. The DSC.03 and DSC.04 strains showed the highest CMCase and FPase activities, respectively. Subsequently, molecular identification and phylogenetic analysis confirmed DSC.03 (PP851408.1) and DSC.04 (PP851410.1) isolates as Bacillus subtilis and Bacillus velezensis, respectively. The maximum bio-degradation percentages were 86.85% for filter paper and 48.72% for dry DS powder, which occurred in the mixed-culture treatment of the two selected strains after 15 days of incubation under shaking conditions at 150 rpm and 37°C. These findings indicate for the first time that natural durian shell compost contains potential cellulose-degrading bacterial communities with high extracellular enzyme-producing ability and active interactions with each other, which can be beneficial for the fermentation or composting of DS waste.

Abstract. Karnila R, Hasan B, Iriani D, Putra HS, Fauzi M, Zulfarina. 2024. Preparation and characterization of chitosan derived from slipper lobster (Thenus orientalis). Biodiversitas 25: 4360-4369. Slipper lobster (Thenus orientalis (Lund, 1793)) is a marine fishery commodity that can be utilized its large carapace (proportion >50%) to be converted into chitosan, but ideal, accurate and rapid characterization has not been developed in detecting chitosan and its derivatives as potential raw materials for nutraceuticals. In this study, the proportion and chemical composition of fan shrimp were analyzed, and the carapace of fan shrimp was determined for the degree of deacetylation of chitin and chitosan, then chitosan was evaluated for glycosidic chains using LCMS-MS from ESI sources. The method used was descriptive with 3 repetitions. The results showed that the largest proportion of the fan shrimp body was found in the carapace at 52.98%. The highest mineral content in the carapace is calcium at 752 mg/L and the lowest is phosphorus at 0.36 mg/L and higher than meat. The yield value of chitosan was 31.19% with a deacetylation degree of 80.15%. The glycosidic chain of chitosan has many amine groups from the structure of the compound 2-Amino-2-Deoxy-D-Glucose Chitosamine and 2-(Aminomethyl)-N-(3-isopropyl octahydro [1,2,4] triazolo [4,3-a] pyridine-6-il)-1 piperidinekar kotakamida which have high quality chitosan affinity, but there is a compound 5-Aminomethyl-2,4-Dihydro [1,2,4] Triazol-3-One Hydrochloride and N-[3-Methyl-2-(4-methyl-1-piperazinyl)-butyl] isoleucinamide hydrochloride which tends to be dissociated and cationized by HCl. Overall, these data suggest the glycosidic chain of slipper lobster has potential as a raw material for nutraceuticals and functional food ingredients.

Abstract. Atni OK, Munir E, Pasaribu N. 2024. Diversity of bioactive compounds from Parmotrema xanthinum as antimicrobial potential through in-vitro and in-silico assessment. Biodiversitas 25: 4438-4449. Lichens, integral to ecosystem diversity, are known for producing bioactive secondary metabolites with significant pharmacological applications, particularly in antimicrobial therapies. This study evaluates the antimicrobial potential of Parmotrema xanthinum through in vitro and in silico approaches, emphasizing its role in biodiversity and drug discovery. Methanol extracts of P. xanthinum were tested against Gram-negative and Gram-positive bacteria, as well as pathogenic yeast, using the disc diffusion method. The extracts exhibited notable antimicrobial activity, particularly against Escherichia coli (18.6 ± 0.44 mm) and Salmonella enterica serovar Typhi (15.8 ± 0.25 mm). Gas chromatography-mass spectrometry (GC-MS) analysis identified 29 bioactive compounds, evaluated for drug-likeness using Lipinski's rule of five and biological activity predictions. Molecular docking studies with penicillin-binding protein 3 (PBP3) of Pseudomonas aeruginosa (PDB ID: 6I1E) revealed strong binding affinities. Notably, benzenepropanoic acid, ?-(2,5-dioxopyrrolo)-, exhibited a binding energy of -5.9 kcal/mol, while 2,2,3,3-tetramethylcyclopropanoic acid, phenyl ester, showed -5.2 kcal/mol. These findings highlight P. xanthinum as a valuable source of bioactive compounds with potential for combating bacterial resistance. Further investigations into its bioactive mechanisms, pharmacodynamics, and safety profiles are recommended to advance its development as a viable candidate for antimicrobial drug discovery.
