A 63-year-old male presented with sudden diminution of vision, eye discomfort, redness and watering in his left eye. He had undergone glaucoma valve filtering surgery for refractive secondary glaucoma one week back. He also had a history of failed augmented trabeculectomy one year earlier in the same eye. Ocular examination showed best corrected visual acuity(BCVA) of 6/18 and there was a bleb leak, shallow anterior chamber and intraocular pression(IOP) of 6mmHg. Successful sealing of bleb leak was performed using fibrin glue resulted in deepening of anterior chamber with IOP of 13mmHg. This case demonstrates that, fibrin glue is an effective method for management of early filtering bleb leak.

Background: Infection with Mycobacterium tuberculosis, the causative agent of TB, is responsible for one of the global epidemics. Thus, new drugs are needed that do not confer cross-resistance with currently administered front-line therapeutics. Quinoline-based natural products and synthetic derivatives have been extensively explored for antitubercular activity.
Objective: The main goal of this study was to prepare a collection of benzylated 8-hydroxyquinoline derivatives through synthesis and assess their antitubercular activity along with a molecular docking study to clarify their biological mechanism of action.
Methodology: The benzylated 8-hydroxyquinoline derivatives were synthesized using Williamson synthesis methods. Antitubercular activity was assessed against fast replicating M. tuberculosis H??Rv using Microplate Alamar Blue Assay (MABA) and non-replicating cultures using Low-Oxygen Recovery Assay (LORA). Molecular docking studies were carried out against enoyl-acyl carrier protein reductase (InhA).
Results: Five benzylated 8-hydroxyquinoline derivatives were synthesized in moderate yields and characterized using NMR spectroscopy. MABA and LORA assays indicate compounds 3-5 as the most inhibitory derivatives with MIC90's ranging from 6.38 to 54.28 ?M. Molecular docking against InhA showed modest 90 binding energies for compounds 4 (-8.5 kcal/mol) and 5 (-8.6 kcal/mol).
Conclusion: Findings suggest a rationale for the further evolution of this promising series of antitubercular quinoline small molecules. Structure-activity analysis shows that an 8-benzyl moiety with chlorine atom/s is important for improved activity against replicating and non-replicating M. tb. H??Rv. This is also supported by our in silico studies.
