Abstract

Cancer is still one of the leading causes of death in the world. Angiogenesis is the formation of new blood vessels, which plays a vital role in the growth of cancer cells. As a result, inhibition of proangiogenic factors such as vascular epidermal growth factor (VEGF) could be used as a cancer treatment strategy. Black garlic (BG) is processed fresh garlic (Allium sativum L.) for several days under controlled high temperature and humidity. The research aims to investigate the effect of Indonesian local BG on antiangiogenic activity through in vivo and in silico studies. The in vivo test was carried out by observing the formation of new blood vessels using the Chorio-Allantoic Membrane Assay (CAM). The in silico study was performed by docking analysis of BG bioactive compounds on the VEGF receptor (VEGFR). The results showed that ethanol extract, ethyl acetate fraction, and n-hexane fraction of BG inhibit new vessel blood formation, with n-hexane fraction having the highest efficacy. The molecular docking assay indicated some similarities in the amino acids involved in the interaction between the BG bioactive compounds and the native ligand in binding to VEGFR. This similarity may lead to interference with VEGFR resulting in angiogenesis inhibition. The study suggests that BG has the potential to be developed as an anticancer agent, which might be through the mechanism of inhibiting the angiogenesis process

Abstract

Thermochemistry has abstract and mathematical material which makes it difficult for students to understand this material. Students are required to discuss this material in depth so teaching materials are needed that support student learning flexibly. Thus, the research purpose is to develop a thermochemistry e-worksheet based on FGIL for high school students in phase F. The research type is R&D with the ADDIE model which is limited to the Development stage. Content validity was carried out with four validators and practicality was obtained from 36 phases F high school students. The research instruments were validation sheets and student response questionnaires. The validity value is determined by Aiken's V test, if the V value is > 0.40 then an aspect is declared valid. The research findings demonstrated that the average assessment on the material aspect was 0.92 (very valid); the media aspect 0.96 (very valid); and the language aspect was 0.83 (very valid), while the average percentage of student responses was 96% (very practical). So, it can be said that the developed thermochemistry e-worksheet based on FGIL is valid and practical to use.
