Background: The discovery and development of anticancer still remain a challenge especially regarding the problem of cancer cell selectivity. Matrix metalloproteinase (MMP) was broadly studied as one of the protein targets to stop cancer angiogenesis as well as its cell migration. Main text: The MMP degrades extracellular matrix (ECM) such as collagen and gelatin which are important to control the cell migration from one to other sites. In cancer, this cell migration is regarded with metastasis, which is essential for the formation of new blood vessels called angiogenesis. The most common target in MMP, i.e. the catalytic site, is currently reported as being the non-selective target for inhibitor compounds that inhibit all MMPs but is associated with adverse side effects. Hemopexin, especially in MMP9 (PEX9) was found to be different from other domains in the MMP family which could potentially be the next target for anticancer due to the availability of its crystal structure in the Protein Data Bank (PDB). Conclusion: The PEX9 crystal structure was resolved as a homodimer connected by a hydrophobic area between two blades along the β-propeller which its structure and function for computational drug modelling can be studied.
The H1N1 pandemic in 2009 and the H5N1 outbreak in 2005 have shocked the world as millions of people were infected and hundreds of thousands died due to the infections by the influenza virus. Oseltamivir, the most common drug to block the viral life cycle by inhibiting neuraminidase (NA) enzyme, has been less effective in some resistant cases due to the virus mutation. Presently, the binding of 10 chalcone derivatives towards H5N1 and H1N1 NAs in the non-catalytic and catalytic sites was studied using molecular docking. The in silico study was also conducted for its drug-like likeness such as Lipinski Rule, mutagenicity, toxicity and pharmacokinetic profiles. The result demonstrates that two chalcones (1c and 2b) have the potential for future NA inhibitor development. Compound 1c inhibits H5N1 NA and H1N1 NA with IC50 of 27.63 µM and 28.11 µM, respectively, whereas compound 2b inhibits NAs with IC50 of 87.54 µM and 73.17 µM for H5N1 and H1N1, respectively. The in silico drug-like likeness prediction reveals that 1c is 62% better than 2b (58%) in meeting the criteria. The results suggested that 1c and 2b have potencies to be developed as non-competitive inhibitors of neuraminidase for the future development of anti-influenza drugs.
The aim of this research is to investigate the anti-inflammatory activity of avocado peel against carrageenan-induced inflammation in mice. The group of mice that was used as a negative control group to test the anti-inflammatory activity of infusion and decoction (group I) were given aquadest, while the group for testing the activity of extract (group II) was given CMC-Na. The positive control group (group III) was given potassium diclofenac. Groups IV-VI were given avocado peel infusion with the following doses 667.5; 1335; and 2670 mg/kgBW respectively. Groups VII-IX were given avocado peel decoction with the same doses as the previous groups. Groups X-XII were given 830; 1670; and 3330 mg/kgBW of avocado peel extract respectively. The paw edema were measured using a digital caliper for 6 hours afterwards after carrageenan injection. There were a significant (p<0.05) reduction in paw edema at all doses of infusion, decoction, and extract of avocado peel. Based on the research, it can be concluded that the avocado peels have anti-inflammatory activities.
E-milk is one of the products produced by TIP CORP, a study group engaged in the field of entrepreneurship. The application of clean production in the industry has a positive influence on the companies that implement it, both financially and non-financially. The number of milk spills in the packaging process makes the results less than the maximum so that it is necessary to apply the potential of clean production with the calculation of the net production feasibility analysis, from the calculation of the pay back period of the purchase of a liquid filling machine is 3.8 months. Potential implementation of cleaner production needs to be done because it can help prevent and reduce environmental impacts through the product life cycle.
