Abstract

Observation of molecular docking results was generally performed by analyzing the docking score and the interacting amino acid residues separately either in tables or graphs. Sometimes it was not easy to rank the tested ligands’ docking results, especially if there were many ligands. This study aims to introduce a new way to analyze docking results with a two‐dimensional graph between the difference in docking score and the similarity of ligand‐receptor interactions. Molecular docking was performed with one reference ligand and several test ligands. The docking score difference was obtained between the test and the reference ligands as the graph’s x‐axis. Meanwhile, the y‐axis contains the similarity of ligand‐receptor interactions, obtained from the ratio of amino acid residues and the types of interactions between the test and reference ligands. Docking result analysis was more straightforward because two critical parameters were presented in one graph. This graph could be used to support the analysis of the docking results.

Abstract

Abstract. The independence of food supply in Indonesia is supported by the abundant diversity of natural ingredients from vegetable, animal and mineral sources. Compared to drugs, dependence on food products in other countries is relatively lower, because the fabrication requires facilities and infrastructure that can be fulfilled domestically. The regulatory system managed by the Republic of Indonesia Drug and Food Control Agency (BPOM-RI) has been implemented to ensure that food products consumed by the public are of high quality, nutritious, safe, halal, and affordable and with a taste that satisfies user communities. Circular-worthy products must at least meet the registration requirements of halal aspects, maximum microbial limits and chemical contamination. The growth of Micro, Small and Medium Enterprises (MSMEs) is also facilitated by the government. Dharma Boga is one of the Small and Medium Enterprises (UKM) in Klangon sub-district, Bojonegoro which is engaged in food production for more than 10 years. Some problems related to registration, halal certification and handling of production, especially food additives that meet requirements, has been communicated to the Community Service Team (PENMAS) Faculty of Pharmacy, Airlangga University (FFUA). Alhamdulillah, PENMAS activities with training materials on how to produce and register good and halal food have been carried out with satisfactory results, although it still needs to be followed up with a partnership for the MSME revitalization program in the future. Of the three parameters used to measure participants' understanding of training material, the average obtained more than 30% showed an increase. For the introduction of the halal logo and the dangers of formaldehyde, 100% of the message is understood. The training involved experts and stakeholders in the authority of the East Java Indonesian Ulama Council and the teaching staff and the Airlangga University Faculty of Pharmacy Testing Service Unit.         Abstrak. Kemandirian penyediaan pangan di Indonesia didukung oleh diversitas bahan alam yang melimpah baik dari sumber nabati, hewani, maupun mineral. Dibandingkan obat, ketergantungan produk pangan pada negara lain relatif lebih rendah, karena fabrikasinya membutuhkan fasilitas dan infrastruktur yang dapat terpenuhi di dalam negeri. Sistem regulasi yang dikelola oleh Badan Pengawas Obat dan Makanan Republik Indonesia (BPOM-RI) telah diberlakukan untuk menjamin produk makanan yang dikonsumsi masyarakat berkualitas, bergizi, aman, halal, dan terjangkau serta dengan rasa yang memuaskan selera masyarakat. Produk yang laik edar minimal harus memenuhi persyaratan registrasi dari aspek halal, batas maksimum mikroba dan cemaran bahan kimia. Tumbuh kembangnya Usaha Mikro, Kecil dan Menengah (UMKM) juga difasilitasi oleh pemerintah. Dharma Boga adalah salah satu Usaha Kecil Menengah (UKM) di kecamatan Klangon, Bojonegoro yang bergerak dibidang produksi makanan selama lebih dari 10 tahun. Beberapa permasalahan terkait registrasi, sertifikasi halal dan penanganan produksi terutama bahan tambahan makanan yang memenuhi persyaratan, telah dikomunikasikan kepada Tim Pengabdian kepada Masyarakat (PENMAS) Fakultas Farmasi Univeritas Airlangga (FFUA). Alhamdulillah kegiatan PENMAS dengan materi pelatihan cara produksi dan registrasi pangan yang baik serta halal telah dilaksanakan dengan hasil yang memuaskan, walaupun masih perlu ditindaklanjuti dengan jalinan kerjasama untuk program revitalisasi UMKM di masa mendatang. Dari tiga parameter yang digunakan untuk mengukur pemahaman peserta terhadap materi pelatihan, rerata yang diperoleh lebih dari 30% menunjukkan peningkatan. Untuk pengenalan logo halal dan bahaya formalin, 100% peserta sudah paham. Pelatihan melibatkan pakar dan pemangku kewenangan dari Majelis Ulama Indonesia Jawa Timur dan para staf pengajar serta Unit Layanan Pengujian Fakultas Farmasi Universitas Airlangga.

Abstract

Andrographolide, a diterpenoid lactone isolated from the herb of Andrographis paniculata and known to possess antitumor activity in breast cancer models was subjected to semisynthesis leading to the preparation of a number of derivatives. After protection of the two hydroxyl groups present at C-3 and C-19 to give 3,19-isopropylidene and 3,19-benzylidene andrographolides, the remaining hydroxyl group at C-14 of andrographolide was treated with acid anhydride or acid chloride under base condition. Unfortunately, the reactions gave only 14-dehydroandrographolide as well as unidentified diacyl compounds in replace of the target molecule 14-O-acyl andrographolide. An alternative procedure using neat acetic anhydride under reflux gave the acetyl derivatives. The resulted compounds exhibited cytotoxic activity against MCF-7 breast cancer cells with better growth inhibition than the parent compound andrographolide.

Abstract

This study aims to describe various studies related to synthesizing flavanone derivatives using the microwave-assisted method with a bibliometric approach. Metadata information was collected from Scopus on June 30th, 2023, with three keywords (microwave-assisted OR microwave, synthesis, and flavanone) searched for article titles, abstracts, and keywords. Analysis and research mapping were carried out with VOSviewer. Of the 33 articles relevant for analysis, 15 keyword clusters were obtained, most of which contained a list of flavanone derivatives. Interestingly, none of these clusters contain keywords for well-known compounds from the flavanone group, such as pinostrobin, pinocembrin, or hesperetin. In other words, there is an excellent opportunity to obtain novelty for microwave-assisted derivatization studies of flavanones. The chances of publication of these studies are greater in Chemistry of Heterocyclic Compounds (Springer Nature), Oriental Journal of Chemistry (Scientific Publishers), and Tetrahedron Letters (Elsevier), each with three documents. Meanwhile, most researchers on this topic come from India with 13 documents. This information allows researchers on this topic to determine potential flavanones that have the opportunity to be derivatized by the microwave-assisted method.
