Clinicopathological Study of Mucormycosis at Varied Sites During the COVID-19 Pandemic.

Background: Mucormycosis, also known as black fungus, is a rare but serious fungal infection caused by mucor that belongs to Zygomycotic species. Mucor is characterized by non-septate, irregularly wide hyphae with right-angle branching. Mucor can infect different systems of the body and manifest differently depending on the location of the infection, which includes pulmonary, gastrointestinal, rhino-cerebral, and cutaneous.

Discovery of potent dual ligands for dopamine D4 and σ1 receptors.

During our work on exploration of molecules with some piperidine-triazole scaffolds, we realized that our compounds display chemical similarity with some σ, as well as dopaminergic receptor ligands. Here we show that this series of molecules has indeed strong affinity both for σ1 and dopamine D4 receptors. Moreover, they appear selective towards σ2, dopamine paralogues D1, D2, D3 and D5 receptors and hERG channel.

Synthesis and biological studies of new piperidino-1,2,3-triazole hybrids with 3-aryl isoxazole side chains.

A small library of new piperidine-triazole hybrids with 3-aryl isoxazole side chains has been designed and synthesized. Their cytotoxicity against a panel of seven cancer cell lines has been established. For the most promising compound, an IC value of 3.

Synthesis of pyrazolo[3,4-d]pyrimidin-4(5H)-ones tethered to 1,2,3-triazoles and their evaluation as potential anticancer agents.

A series of hybrid aza heterocycles containing pyrazolo[3,4-d]pyrimidin-4(5H)-ones tethered to 1,2,3-triazole scaffold were synthesized from 1,3-dipolar cycloaddition reaction of pyrazolopyrimidinone based alkyne with azides using Cu(II) catalyst in presence of sodium ascorbate and evaluated for their anticancer efficacy in vitro against C6 rat and U87 human glioma cell lines. These compounds induced a concentration dependent inhibition of C6 rat and U87 human glioma cell proliferation. Compound 5f arrested the cells at S-phase of the cell cycle and induced apoptosis in U87 GBM cell lines.
