Abstract

Indonesia merupakan negara yang kaya akan biota laut, salah satunya adalah makro alga. Pembuatan review artikel ini dilakukan untuk menambah pengetahuan tentang ilmu bahari khususnya dalam isolasi metabolit sekunder pada makro alga. Kelompok makro alga atau lebih dikenal dengan sebutan rumput laut merupakan tumbuhan tingkat rendah yang memproduksi senyawa metabolit sekunder. Isolasi pada makro alga menunjukkan adanya senyawa metabolit sekunder yang terkandung (flavonoid, steroid, terpenoid, alkaloid, fenol, saponin). Metode yang digunakan pada review ini merupakan suatu tinjauan literatur (literatur review) terhadap lima jurnal dan berdasarkan teori-teori yang relevan. Adapun untuk mendapatkan ekstrak sampel dilakukan teknik yang sama yaitu maserasi menggunakan pelarut yang sesuai karakteristik zat yang akan diisolasi selama 1-3 hari. Sedangkan untuk mengisolasi senyawa metabolit sekunder digunakan teknik kromatografi kolom, kromatografi gas-spektometri massa (GC-MS) dan kromatografi lapis tipis (KLT).

Abstract

The increasing prevalence of antibiotic-resistant bacteria poses a critical global health concern, necessitating the exploration of novel antibacterial solutions. Endophytic bacteria, which colonize plant tissues without causing harm, have gained attention as potential sources of bioactive metabolites. This study aimed to isolate and characterize endophytic bacteria from Bambusa vulgaris leaves and evaluate their antibacterial potential against pathogenic microorganisms. Leaf samples were collected from Bekasi, West Java, and subjected to a surface sterilization process prior to bacterial isolation. A total of 12 bacterial strains were successfully obtained and screened for antibacterial activity against Bacillus subtilis, Propionibacterium acnes, Pseudomonas aeruginosa, and Staphylococcus epidermidis using the agar well diffusion assay. Three isolates exhibited notable inhibitory activity, with P8 demonstrating the strongest antibacterial effects against B. subtilis, P. acnes, and S. epidermidis. The two most potent isolates, P8 and K3, were characterized via 16S rRNA gene sequencing. Genomic DNA extraction was performed, followed by Polymerase Chain Reaction (PCR) amplification using the universal primers 27F (5′-AGAGTTTGATYMTGGCTCAG-3′) and 1492R (5′-GGTTACCTTGTTACGACTT-3′). Sequencing and The Basic Local Alignment Search Tool (BLAST) analysis confirmed that isolate P8 exhibited 100% similarity to B. subtilis strain LZH-H1, whereas isolate K3 shared 99.85% similarity with Pantoea stewartii subsp. indologenes strain SR2-12. These findings suggest that endophytic bacteria from B. vulgaris endohytic bacteria hold promise as potential sources of antibacterial compounds. Further research is necessary to purify and characterize these bioactive metabolites for potential pharmaceutical applications.

Abstract

Parkinson's disease is a degenerative nervous system disorder caused by the death of dopamine-producing cells in the substantia nigra. Dopaminergic treatment could alleviate motor symptoms for a period. One of the effective dopaminergic medications for symptomatic relief was Levodopa and dopamine agonists. Clinically, Levodopa was always combined with Dopa Decarboxylase (DDC) inhibitors, which redirected Levodopa metabolism towards the COMT pathway, increasing its bioavailability in the central nervous system. The purpose of this article was to investigate the relationship between COMT and MAO-B gene polymorphisms and Levodopa in Parkinson's disease patients, starting by gathering literature on the association between COMT and MAO-B polymorphisms and Levodopa in Parkinson's disease patients using various databases. Reviewed literature revealed that the most frequent polymorphism in the COMT gene was rs4680. Some polymorphisms significantly impacted the treatment of Parkinson's disease patients. However, despite efforts to identify genetic factors influencing the risk of side effects or treatment ineffectiveness, the role of pharmacogenetics in Parkinson's disease has not been fully explored and lacks consistent clinical recommendations. Further research was needed to tailor treatment to individual polymorphisms so that pharmacogenomic approaches could be applied more consistently
