It presents with a range of clinical symptoms, a low death rate, and a high morbidity rate, which contributes to social discrimination. This condition has major effects on people's socioeconomic circumstances. This illness is carried by mosquitoes that have spread malaria. Lymphatic filariasis, caused by Wuchereria bancrofti, Brugia malayi, and Brugia timori, is a crippling illness with serious social and economic consequences. The infection persisted despite therapy with conventional antifilarial medications such as diethylcarbamazine (DEC), albendazole, and ivermectin, which are mostly microfilaricides. Current treatments (ivermectin, diethylcarbamazine, and albendazole) have limited effectiveness against adult parasites and produce side effects; therefore, innovative antifilarial medications are urgently required. Hence, macrofilaricides, embryostatic agents, and improved microfilaricides are required. The following article discusses the typical synthetic methodologies established for antifilarial activity as well as their marketed pharmaceuticals, which will help researchers, medicinal chemists, and pharmaceutical scientists to develop new and effective antifilarial therapies. This review can help to identify new lead compounds and optimize existing commercial medications to improve their therapeutic efficacy.

It arises due to the inability of the body to produce enough insulin (the hormone responsible for controlling blood sugar levels) or inability to utilize the insulin, leading to hyperglycaemic condition, which, if left uncontrolled gives rise to chronic microvascular and macrovascular complications like retinopathy, neuropathy, nephropathy, coronary artery disease, cognitive impairment, etc. Several therapeutic approaches are available for the treatment of diabetes; among which dipeptidyl peptidase (DPP-IV) inhibitors (gliptins) hold a significant place. DPP-IV is a multifunctional enzyme or a serine exopeptidase that plays an imperative role in cleaving bioactive molecules. DPP-IV causes the breakdown of incretin hormone (GLP-1: Glucagon-like peptide 1 and GIP: Glucose-dependent insulinotropic peptide) that is essential for controlling glycaemic levels in the body. Inhibition of DPP-IV enzyme (DPP-IV inhibitors: Sitagliptin, Saxagliptin, Linagliptin, Alogliptin) prevents this breakdown, thereby controlling blood glucose levels and saving the patients from deleterious effects of prolonged hyperglycaemic conditions. Triazole-based DPP-IV inhibitors are a significant class of drugs used to treat Type 2 diabetes mellitus in a dose-dependent manner.
