Abstract

Diabetes is a chronic disease with increasing prevalence and is becoming a global health threat. One plant that is efficacious for lowering blood sugar levels is matcha tea which can be made into a processed product in the form of jelly candy. This community service aims to increase understanding and train the community to make jelly candy food products from matcha which comes from agricultural products for complementary therapy for diabetes mellitus. This community service was carried out in Kalisegoro Village. The participants in this service activity were 25 PKK women and was carried out in three stages. The first stage will be a meeting and coordination with the village head and the PKK women's group who will conduct training in making jelly candy. The second stage is the activity of preparing material and preparing practical methods. The third stage, namely coaching and training, includes providing material to training participants by theory and demonstrations. The results of this community service found that 20 people out of 25 participants could answer pretest questions related to the causes of disease and natural treatment for diabetes mellitus. The results of the jelly candy-making tutorial showed that as many as 20 participants could answer post-test questions and understand how to make the product. Based on the results of oral questions and answers, it was found that as many as 15 participants were interested in continuing the results of their service by making their food at home and using it as a family dinner.

Abstract

Diabetes Mellitus (DM) tipe II merupakan penyakit kronis yang prevalensinya semakin meningkat setiap tahunnya. Salah satu strategi terapi untuk pengobatan DM tipe II melalui penghambatan enzim α-glucosidase. Dalam beberapa tahun terakhir, pencarian obat antidiabetes alami semakin populer. Ekstrak batang kayu manis (Cinnamomum burmanni) diketahui berpotensi sebagai antidiabetes. Penelitian ini bertujuan untuk mengidentifikasi senyawa metabolit sekunder dari batang kayu manis (Cinnamomum burmanni) yang paling potensial sebagai inhibitor α-glucosidase secara in silico. Sembilan senyawa metabolit sekunder hasil isolasi batang kayu manis dari penelitian sebelumnya dilakukan penambatan molekul terhadap enzim α-glucosidase kode PDB 2JKE dengan pembanding miglitol dan dianalisis berdasarkan energi pengikatannya. Hasil penelitian menunjukkan bahwa kode PDB 2JKE valid dengan nilai RMSD 0,2912 Å. Berdasarkan analisis penambatan molekul, senyawa nerolidol memiliki score docking (-81,165) yang lebih kecil dibandingkan miglitol (-80,2642) sehingga secara teoritis senyawa nerolidol memiliki penghambatan yang lebih baik terhadap enzim α-glucosidase dibandingkan miglitol. Selain itu, profil ADMET menunjukkan bahwa nerolidol tidak melanggar Lipinski Rules dan tidak toksik.

Abstract

Ipomoea reptans Poir leaves contain phenolic and flavonoid compounds that can reduce free radicals and prevent diseases such as cardiovascular disease, coronary heart disease, and cancer. The drawback of conventional extraction is that it takes a long time, so a shorter extraction method is needed, one of which is the ultrasonic method. This study aims to test the antioxidant activity of ethanol extract of Ipomoea reptans Poir leaves extracted by ultrasonic method and determine the total phenolic and flavonoid content. Ipomoea reptans Poir leaves were extracted using the ultrasonic method at 50oC for 30 minutes with 70% ethanol solvent to obtain ethanol extract of Ipomoea reptans Poir leaves. Antioxidant activity test of ethanol extract of Ipomoea reptans Poir leaves using DPPH method and vitamin C as a comparison. Determination of total phenolic content using gallic acid with a maximum wavelength of 745.20 nm and operating time of 120 minutes. Determination of total flavonoid content using quercetin with a wavelength of 439.60 nm and operating time of 30 minutes. The results showed that the antioxidant activity of Ipomoea reptans Poir leaves obtained an IC50 value of 40.62 ppm (very strong). Total phenolic and flavonoids were 78.33 mgGAE/g extract and 1.03 mgQE/g extract.

Abstract

Fluoro-hydroxyxanthone derivatives (X1–X10) were investigated as potential inhibitors of estrogen receptor alpha (ER-α) through molecular docking and in silico ADMET profiling. The docking protocol was validated through a redocking procedure, yielding a Root Mean Square Deviation (RMSD) of 0.81 Å, which confirmed the method's reliability.  Compounds X6–X10 demonstrated favorable binding affinities ranging from −7.32 to −7.46 kcal/mol, although these values remained lower than those of the native ligand, estradiol (−10.69 kcal/mol), and tamoxifen (−9.21 kcal/mol). These compounds formed key hydrogen bond interactions with Glu353 and Arg394, similar to estradiol, suggesting a correct binding orientation within the receptor's ligand-binding domain. Structural modifications, particularly the introduction of hydroxyl and fluoro substituents, contributed to the enhanced binding energies observed in these top-performing compounds. ADMET analysis further indicated that compounds X6–X10 complied with Lipinski's Rule of Five, had acceptable oral bioavailability, metabolic stability, and the ability to cross the blood–brain barrier. However, all derivatives were predicted to exhibit mutagenic potential and hepatotoxicity, which may limit their safety profiles. In conclusion, fluoro-hydroxyxanthone derivatives, especially X6–X10, represent promising molecular scaffolds for further optimization and development as potential anti-breast cancer agents targeting ER-α
