Carbocyclic is an organic cyclic compound that has all its carbon atoms arranged in rings. A large variety of heterocyclic compounds are designed and synthesized. The heterocyclic compounds are those cyclic molecules where one or more of the ring carbons are replaced by nitrogen, oxygen, sulfur etc. Heterocycles contain nitrogen atoms such as quinolines, indoles, pyrazine, isoindole, pyrrole, pyridine, imidazole, azocine, thiazoles, etc. (Figure 1). Synthesis is always a desirable field in organic chemistry since it demonstrates a variety of biological activities. Due to their diverse biodynamic properties, quinoline, indole, and their derivatives have a special place in the chemistry of nitrogen-containing heterocyclic molecules. The significance of indole can be documented both by the ever increasing number of publications (more than 80,000 in the 20th century) that target chemistry and by its presence in pharmaceuticals, fragrances, agrochemicals, pigments, material science, organic electronics, and natural products. objective: 1. To find out the potential protein responsible for antibacterial activity. 2. To study the interaction study of heterocyclic compounds with specific protein. 3. To optimize the molecular interaction through machine learning approach. method: Molecular docking study and Machine learning approach result: we examine the molecular coupling of drugs with heterocyclic compounds against the E. coli Sarcin-Ricin Loop RNA with an alteration of C-2667-2'-OCF3 (PDB ID: 6ZYB). These compounds in silico molecular docking analysis showed that they exhibit strong binding affinities, adequate residual interactions, and hydrogen bonding interactions with the protein Sarcin-Ricin Loop RNA from E. coli with a C-2667-2'-OCF3 alteration, indicating potential bioactivity. The binding affinity value for heterocyclic compounds 1-9 is -5.3 to -10.1 Kcal/mol. Many residues exhibit interactions with heterocyclic molecules, according to the findings of this study. Some of the identified amino acids are A:G2648, A:C2649, A:A2670, A:G2671, A:G2669, A:U2650, A:QSK2667, A:G2668, A:C2651, A:C2652, A:U2653, A:C2666, A:A2665 A:QSK2667, A:U2672, A:U2650 & A:A2654 many more. The Machine learning tool is also used to choose the best analysis of molecular descriptors. For these classifiers, molecular descriptor dataset is taken, which shows that training accuracy and testing accuracy is very high and crucial for developing similar antibacterial drugs in near future. conclusion: In the near future, powerful antibacterial treatments could be developed using heterocyclic compounds, which shows how useful it is to do research to identify potential effective antibiotic drugs.

In this context the world has witnessed the pandemic of the human Coronavirus disease (COVID-19) recently. The disease is caused by the Coronavirus namely Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV- 2). Method and Materia: Developing potential and effective vaccine is also time consuming and challenging. The huge resource of plants around us has rich source of potent antiviral compounds. Some of these molecules may serve as tremendously potent lead molecules whose slight structural modifications may give us highly bioactive antiviral derivatives of phytocompounds. Every geographical region is rich in unique plant biodiversity and hence every corner of the world with rich plant biodiversity can serve as abode for potential magical phytocompounds most of which have not been extensively explored for development of antiviral drug formulations against various viruses like the HIV, HPV etc., and the Coronavirus, also known as SARS-CoV-2 which causes the disease COVID-19. Result: Several phytocompounds from various medicinal plants have already been screened using in silico tools and some of them have yielded promising results establishing themselves as potent lead molecules for development of drugs against the highly mutating SARS-CoV-2 virus and thus these phytocompounds may be beneficial in treating COVID-19 and help human to win the life threatening battle against the deadly virus.

Antimicrobial resistance typically involves various mechanisms, such as drug inactivation or modification, drug target modification, drug uptake restriction, and drug efflux, resulting in decreased antibiotic concentrations within the cell. Antimicrobial resistance has been associated with efflux Pumps, known for their capacity to expel different antibiotics from the cell non-specifically. This makes EPs fascinating targets for creating drugs to combat antimicrobial resistance (AMR). The varied structures of secondary metabolites (phytomolecules) found in plants have positioned them as a promising reservoir of efflux pump inhibitors.

Specific molecules, such as chanaoclavine and niaziridin, exhibited noteworthy potential in reversing the effectiveness of drugs, resulting in a reduction of the MIC of tetracycline by up to 16 times against the tested strain of bacteria. These molecules inhibited the efflux pumps responsible for drug resistance and displayed a stronger affinity for membrane proteins.
