Lipinski’S Rule Of Five

Aim: Malaria is among the most devastating and widespread tropical parasitic diseases. To overcome antimalarial drug resistance, new drugs need to be developed. This study is designed to establish the pharmacokinetic profile and toxicity of nine quinine derivatives as potential antimalarial drugs using in silico approaches by SwissADME and pkCSM. Methodology: The structures of investigated compounds were translated into canonical SMILES format and then submitted to SwissADME web tool that gives free access to physicochemical properties, pharmacokinetics, drug-likeness and medicinal chemistry friendliness of compounds, and pkCSM webserver for predicting and optimizing pharmacokinetic and toxicity properties. Results: SwissADME mainly used to predict the physicochemical properties of compounds and their drug-likeness revealed that all quinine derivatives have good bioavailability and satisfied the Lipinski’s rule of five. The pkCSM results on the absorption, distribution, metabolism, excretion and toxicity show  that all investigated compounds have a good pharmacokinetic profile and they are safe since they belong to class 4 of the Globally Harmonized System (300 < Category 4 ≤ 2000 mg/kg/day). Conclusion: Drug-likeness and ADME/T predictions of nine investigated quinine derivatives revealed that they are good candidates to oral drug formulation and thus they can be used in a broader context of overcoming the development of resistance by Plasmodium protozoans against most of the drugs currently used to treat malaria. As future prospects, further studies on bioevaluation of compounds are needed to elucidate their potential pharmacological activities.

Background: Diabetes affects millions of people worldwide, with predicted numbers of about 700 million adults affected by 2045. Among the several anti-diabetic drug therapies available in the market, Dipeptidyl Peptidase-4 (DPP-4) inhibitors have emerged as a promising therapeutic approach with scope for exploration in the segment of peptidomimetics. Objective: Series of proline-containing peptidomimetic compounds were designed and investigated for their drug-likeness through Lipinski’s rule of five, lead-likeness through the rule of three, predictive pharmacokinetic studies (absorption, distribution, metabolism, and excretion), and toxicity properties through in-silico approaches. The designed compounds were evaluated for their interactions with binding sites of the enzyme DPP-4 using an extra precision docking approach. Methods: Proline-containing peptidomimetic compounds were designed rationally. Drug-likeness and lead-likeness properties were calculated using Schrödinger Maestro v11.2 software. ADME and toxicity properties were predicted using PreADMET version 2.0. Docking study was performed using Schrödinger Maestro v11.2 software, and ligands for the study were designed using MarvinSketch software. Results: 5(S)-methyl-L-proline containing 17 ligands were designed. All of them were found to obey Lipinski’s rule of five. Compounds were found to have good ADME profile and low toxicity predictions. Conclusion: Four compounds were found to have good interactions with DPP-4 binding sites and hence created the scope to develop a DPP-4 inhibitors containing 5(S)-methyl-L-proline moiety.

Lipinski’S Rule Of Five

Neurodegenerative diseases have been characterized by loss of neuron structures as well as their functions. This study was designed to assess molecular docking of flavonoids from Andrographis paniculata as potential acetylcholinesterase, butyrylcholinesterase, and monoamine oxidase inhibitors in the treatment of neurodegenerative diseases. Eight identified possible inhibitors of acetylcholinesterase, butyrylcholinesterase, and monoamine oxidase from Andrographis paniculata were retrieved from the PubChem database. The molecular docking, ADMET, and Lipinski’s rule of five were examined using different bioinformatic tools. It was shown that only rutin has the highest binding affinity (-12.6 kcal/mol) than the standard used. ADMET results demonstrated that all the eight compounds are druggable candidates except rutin. Also, only tangeritin has a blood-brain barrier (BBB) permeation potential. Hence, it can be deduced that all flavonoid compounds from Andrographis paniculata are orally druggable, which can make them useful in the treatment of neurodegenerative diseases better than donepezil.

The large originator pharmaceutical companies need more and more new compounds for their molecule banks, because high throughput screening (HTS) is still a widely used method to find new hits in the course of the lead discovery. In the design and synthesis of a new compound library, important points are in focus nowadays: Lipinski’s rule of five (RO5); the high Fsp3 character; the use of bioisosteric heterocycles instead of aromatic rings. With said aim in mind, we have synthesized a small compound library of new spiro[cycloalkane-pyridazinones] with 36 members. The compounds with this new scaffold may be useful in various drug discovery projects.

Lipinski’S Rule Of Five

Breast cancer is one of the leading causes of death noticed in women across the world. Of late the most successful treatments rendered are the use of aromatase inhibitors (AIs). In the current study, a two-way approach for the identification of novel leads has been adapted. 81 chemical compounds were assessed to understand their potentiality against aromatase along with the four known drugs. Docking was performed employing the CDOCKER protocol available on the Discovery Studio (DS v4.5). Exemestane has displayed a higher dock score among the known drug candidates and is labeled as reference. Out of 81 ligands 14 have exhibited higher dock scores than the reference. In the second approach, these 14 compounds were utilized for the generation of the pharmacophore. The validated four-featured pharmacophore was then allowed to screen Chembridge database and the potential Hits were obtained after subjecting them to Lipinski’s rule of five and the ADMET properties. Subsequently, the acquired 3,050 Hits were escalated to molecular docking utilizing GOLD v5.0. Finally, the obtained Hits were consequently represented to be ideal lead candidates that were escalated to the MD simulations and binding free energy calculations. Additionally, the gene-disease association was performed to delineate the associated disease caused by CYP19A1.

Susu kambing memiliki komponen protein salah satunya protein β dan secara umum terjadi polimorfisme pada level protein. Perubahan urutan asam amino akibat polimorfisme memungkinkan adanya potensi dihasilkannya peptida bioaktif penghambat enzim pengubah angiotensin (ACEi). Penelitian ini bertujuan untuk menyaring peptida bioaktif yang berpotensi sebagai ACEi dari kasein β kambing beserta polimorfismenya. Penelitian ini dilakukan dengan teknik in silico terhadap sekuen kasein β kambing serta struktur tiga dimensi human testicular ACE. Langkah yang dilakukan dalam penelitian ini meliputi simulasi pemotongan peptida dengan enzim pencernaan (pepsin, tripsin dan kimotripsin), peninjauan karakteristik peptida lalu simulasi docking ligan-reseptor. Tampilan parameter Lipinski’s Rule of Five (Ro5), bioaktivitas dan energi afinitas dipertimbangkan untuk memilih peptida bioaktif. Hasil yang didapat menunjukkan bahwa ditemukan peptida bioaktif yakni INK (Ile-Asp-Lys) yang memiliki kemampuan hampir setara dengan lisinopril (afinitas energi -8,2kkal/mol vs. -8,3kkal/mol). Peptida INK dapat ditemukan dari hasil hidrolisis dari alel A, C, D dan E, sehingga polimorfisme tidak menyebabkan perbedaan produksi peptida bioaktif. Kesimpulan yang dapat diambil yakni kasein β susu kambing jika dicerna dengan enzim pencernaan dapat menghasilkan peptida bioaktif ACEi yakni INK.Identification of Angiotensin Converting Enzyme-inhibitor (ACEi) Bioactive Peptide from Goat Milk β-Casein with It's Polymorphism by In Silico TechniqueAbstractPolymorphism eventually may be occurred at the protein level. Changes in the amino acid sequence due to polymorphism may exhibit a potential action to generate of the angiotensin-converting enzyme inhibitors (ACEi) bioactive peptide. This study is aimed to assess bioactive peptides that have a great potent value as ACEi from goat β casein along with its polymorphism. The research was done by in silico technique on goat β-casein sequence and three-dimensional structure human testicular ACE.

Lipinski’S Rule Of Five

Coronavirus jenis baru SARS-CoV-2 terus meyebabkan penyakit pernapasan, yang dikenal dengan Coronavirus Disease-2019 (COVID-19). COVID-19 dianggap sebagai penyakit pademi global terbesar pada tahun 2020 dan terapi antiviral COVID-19 masih kurang di seluruh dunia. Penelitian saat ini masih berusaha untuk menemukan terapi potensial untuk penyakit tersebut, termasuk dari senyawa alami. Oleh karena itu, penting untuk mengetahui senyawa herbal apa yang paling efektif untuk melawan virus tersebut. Jamu merupakan obat tradisional yang berasal dari tumbuhan herbal di Indonesia dan memiliki beberapa khasiat obat. Penelitian ini dilakukan dengan tujuan untuk menemukan potensi jamu Indonesia dalam terapi COVID-19. Sebanyak 283 senyawa bioaktif dari jamu Indonesia disaring melalui penapisan berdasarkan parameter Lipinski’s Rule of Five dan prediksi ADMET (Absorpsi, Distribusi, Metabolisme, Eksreksi, dan Toksisitas) menggunakan ProTox-II dan SwissADME. Sebanyak 12 senyawa hasil penapisan kemudian dilanjutkan untuk diuji melalui penambatan molekuler terhadap SARS-CoV-2 Main Protease (Mpro) menggunakan AutoDock Vina. Hasil penelitian ini menunjukkan bahwa Kurkuminol D memiliki energi bebas ikatan (ΔG); sebesar -6,9 kkal/mol; dan konstanta inhibisi (Ki); sebesar 2,99 µM; terendah dibandingkan senyawa hasil penapisan lainnya. Namun, tidak ada senyawa hasil penapisan yang memiliki ΔG lebih rendah daripada ΔG kedua kontrol positif, yaitu sebesar –8,2 kkal/mol (Lopinavir) dan –7,8 kkal/mol (Ritonavir). Walaupun 271 senyawa lain tidak memenuhi syarat dalam penapisan, senyawa tersebut mungkin saja memiliki potensial yang lebih tinggi daripada obat standar. Oleh karena itu, penelitian ini dapat menjadi titik awal dalam proses pengembangan obat terapi COVID-19 dari senyawa alami.
