Mutasi tirosin pada residu 220 menjadi sistein (Y220C) dapat menginduksi cavity pada residu 220 sebagai pusatnya. Mutasi ini dapat menurunkan kestabilan termal dan menyebabkan adanya sedikit perubahan pada bagian kontak DNA. p53 reactivation and induction of massive apoptosis-1 (PRIMA-1) terbukti dapat mereaktivasi p53, namun mekanisme dan target residunya belum cukup jelas. Fakta eksperimen menunjukkan PRIMA-1 dapat modifikasi sistein dengan membentuk adduct. Penelitian ini ditujukan untuk mengamati efek dinamis modifikasi sistein menggunakan PRIMA-1, yang disebut adduct PRIMA-sistein pada residu 220 untuk mereaktivasi p53. Modifikasi Y220C dilakukan dengan memaksa adduct PRIMA-sistein masuk ke dalam cavity yang berukuran lebih kecil dibanding struktur adduct tersebut. Pengamatan stabilitas pada level molekuler dilakukan dengan cara simulasi dinamika molekuler (DM). Trajektori-Trajektori yang dihasilkan simulasi dinamika molekul selama 100ns menunjukkan perubahanÂ dinamika karena adanya modifikasi Y220C pada residu nomor 220. Data Backbone B-factor dan order parameter menunjukkan bahwaÂ adanya modifikasi Y220C sebagian mampu menyerupai wild type pada residu 120 yang merupakan daerah yang berfungsi untuk interaksi dengan DNA. Selain itu, pada residu 155 yang berinteraksi langsung dengan residu 220 juga terdapat peningkatan fleksibilitas residu 155 setelah adanya modifikasi Y220C.

The cationic chemosensor based on organic compound bearing an aminophenol moiety as a receptor for metal analyte and a cinnamaldehyde moiety as chromophoric fragment has been developed. In this work, we report the colorimetric sensing of nitrophenyl cinnamaldehyde derivative, namely methyl-3-(2-hidroxy-5-nitrophenyl amino)-3-phenylpropanoate, towards a variety of metal cations, such as Cu2+, Fe3+, Ni2+ and Zn2+. The cation sensing abilities of the sensor were observed for Cu2+and Fe3+ with a color change from colorless to pink and faint yellow, respectively, The characteristic UV-Vis spectra changes were observed upon addition of Cu2+and Fe3+ cations. The hypsochromic absorption spectra shifts were obtained, indicating the cations and sensor complexations had formed. A metal-to-ligand-charge-transfer (MLCT) had occurred and the charge density of the sensor changed resulting in appearance of new absorption peaks in the UV-Vis spectra and color changes of the sensor solution upon addition of the Cu2+and Fe3+.

D6-anhidroeritromisin-A is a new derivative of erythromycin which is synthesized through biosynthetic engineering technique. The molecular docking in rRNA 23S Deinoccocus radiodurans are accomplished to determine the model and strength of binding to the target macromolecule. The molecular docking of erythromycin-A and 6-deoksieritromisin-A to the same macromolecule is used as a control. The docking result of the D6-anhidroeritromisin-A shows that it occupies the same cavity as of the experimental erythromycin-A in the same macromolecule. The binding position of D6-anhidroeritromisin-A is not exactly same as erythromycin-A and 6-deoksieritromisin-A due to the presence of D6 unsaturated double bond. However the hydroxyl group(OH) at C-6 does not have an apparent effect on the binding model to rRNA23S D. radiodurans.

The Petroleum diesel-based fossil fuel remains the primary source of energy consumption in Indonesia. The utilization of this unrenewable fuel depletes fossil fuels; thus, an alternative, renewable fuel, such as one based on biohydrocarbon from biomass-green diesel-could be an option. In this work, green diesel was produced through the hydrodeoxygenation from palm oil and processed in a batch-stirred autoclave reactor over natural zeolite (NZ) and NZ modified with 3 wt.% Fe metal (Fe/NZ) as heterogeneous catalyst. NZ showed high crystallinity and suitability to the simulated pattern of the mordenite and clinoptilolite phases according to X-ray diffraction (XRD) analysis. The presence of Fe metal was further confirmed by XRD, with an additional small diffraction peak of Fe0 that appeared at 2θ = 44-45°. Meanwhile, NZ and Fe/NZ were also characterized by Scanning electron microscopy (SEM) with Energy Dispersive X-ray (EDX), X-ray Fluorescence (XRF), and Surface Area Analyzer (SAA). The obtained materials were tested for the conversion of palm oil into diesel-range hydrocarbons (C15-C18) under conditions of 375 °C and 12 bar H2 for 2 h. NZ and Fe/NZ produced a liquid hydrocarbon with straight-chain (C15-C18) alkanes as the most abundant products. Based on Gas Chromatography-Mass Spectrometry (GC-MS) measurement, a higher conversion of palm oil into diesel-like hydrocarbons reached more than 58% and 89%, when NZ and Fe modified NZ (Fe/NZ), respectively were used as catalysts.

The synthesis of anethole-lauryl methacrylate (LMA) copolymer had been carried out by cationic polymerization using BF3O(C2H5)2 as the initiator without the use of solvent at room temperature (28-30 °C) over atmospheric N2 conditions. Polymerization was conducted by varying LMA concentration i.e. 2%, 4%, and 6%, (w/w) with respect to the anethole weight. Structural determination of co-poly(anethole-LMA) was done using FTIR and 1H-NMR spectrophotometer. The relative molecular weight (Mv) of co-poly (anethole-LMA) was measured by an Ostwald Viscometer at room temperature. Morphological characterization and surface area analysis of co-poly(anethole-LMA) was performed using SEM and SAA, respectively. The successful synthesis of co-poly(anethole-LMA) was proven by the disappearance of vinyl group absorption at 1696, 1638, 965, and 938 cm-1 of the FTIR spectra, as well as the loss of vinyl group proton signals at 6.4-5.5 ppm in the 1H-NMR spectra. Increasing the weight of the LMA affected the characteristics of co-poly(anethole-LMA). The relative molecular weight of co-poly(anethole-LMA) was found to rise by increasing the weight of LMA. The Mv of co-poly(anethole-LMA) 2%, 4%, and 6% were 32378.62, 50611.05, and 65133.79 g/mol, respectively. The morphology of co-poly(anethole-LMA) showed that the surface distance between particles was getting tighter and the highest surface area in co-poly(Anethole-LMA) 6% was 233.80 m2/g.

Coronaviruses have been known since 2002 in the case of SARS (Severe Acute Respiratory Syndrome). SARS-CoV-2, the cause of the COVID-19 pandemic, is believed to be an evolution of the SARS-causing coronavirus (SARS-CoV). This evolution shows the complex interaction dynamics between the virus and the host, which have characterized the emergence of new SARS-CoV-2 strain variations until now. Therefore, the search for these antiviral drugs is still critical. MPro is one of the important proteins for the life cycle of pathogenic coronaviruses, so it is an attractive target for developing drugs that inhibit this virus. This study examined the interaction of teicoplanin derivatives and vancomycin as SARS-CoV-2 MPro (6LU7) inhibitors through molecular docking with Autodock Vina. The smallest RMSD value was selected and stored to calculate the energy value. The image of atoms in the ligand and receptor was processed with Autodock Tools, LigPlus, and PyMOL. The study showed that teicoplanin derivatives such as teicoplanin aglycone, teicoplanin-A3-1, and vancomycin had the potential as SARS-CoV-2 Mpro inhibitors. Based on the interaction at the active site and the obtained ΔG values, even the teicoplanin aglycon had a more significant inhibitory potential than other potent inhibitors such as N3.
