Abstract:: Formic acid (HCOOH) as an inexpensive and versatile reagent has attracted broad attention in the field of green synthesis and chemical industry. Formic acid acts not only as a convenient and less toxic CO surrogate, but also as an excel-lent formylative reagent, C1 source and hydrogen donor in organic reactions. Over the past decades, many exciting contribu-tions have been made which have helped chemists to understand the mechanisms of these reactions. The review will exam-ine recent advances in the utilization of formic acid as economical, practical and multipurpose reactant in synthetic trans-formations.

Heterocyclic compounds are indispensable organic structures because of their promising potential applications in medicinal, pharmaceutical and other related fields of chemistry. Exploring these heterocyclic compounds by evaluating metal nanoparticles as efficient nanocatalysts have attracted the researchers over the past decades, due to their stability, recyclability, reusability rather than conventional catalysts. Most of the nano-catalyzed organic reactions are taking place in benign and under green conditions. In this mini-review, we have documented synthesis of some of the recent N-containing heterocyclic compounds by utilizing advanced nanoparticles as effective catalysts. It has been concluded that exercising these nanocatalysts for the synthesis of N-containing heterocyclic compounds not only enhanced the yield of the product but has extensively increased the selectivity of the desired products via greener approach.

Nitrogen-containing heterocycles are one of the most common structural motifs in approximately 80% of the marketed drugs. Of these, benzimidazoles analogues are known to elicit a wide spectrum of pharmaceutical activities such as anticancer, antibacterial, antiparasitic, antiviral, antifungal as well as chemosensor effect. Based on the benzimidazole core fused heterocyclic compounds, crescent-shaped bisbenzimidazoles were developed which provided an early breakthrough in the sequence-specific DNA recognition. Over the years, a number of functional variations in the bisbenzimidazole core have led to the emergence of their unique properties and established them as versatile ligands against several classes of pathogens. The present review provides an overview of diverse pharmacological activities of the bisbenzimidazole analogues in the past decade with a brief account of its development through the years.

Storage Processes

The theory of storage processes, originally formulated by Moran [1] in 1954, has developed in the past fourteen years into a minor subfield of Applied Probability, closely allied to queueing theory. While dam models with discrete inputs are analogous to queueing processes, the essentially continuous nature of water inflows has distinguished generalized storage processes from queues. Indeed, some of the most complex of storage problems have arisen in the case of continuous flows.
