Dynein is the primary minus-end-directed microtubule motor protein. To achieve activation, dynein binds to the dynactin complex and an adaptor to form the "activated dynein complex." The protein Lis1 aids activation by binding to dynein and promoting its association with dynactin and the adaptor.

Dynein is the primary minus-end-directed microtubule motor [1]. To achieve activation, dynein binds to the dynactin complex and an adaptor to form the "activated dynein complex" [2, 3]. The protein Lis1 aids activation by binding to dynein and promoting its association with dynactin and adaptor [4, 5].

Lipid droplets (LDs), the lipid-rich intracellular organelles, serve to regulate many physiological processes and therefore attention has been attracted towards their selective detection. We report positively solvatochromic lipophilic dyes, based on the push-pull framework containing coumarin-pyridine heterocycles for selective live-cell imaging of lipid droplets (LDs) in Cos-7 and McA-RH7777 cells at ultralow concentrations (200 nM). The fluorescent probes show a remarkable increase in fluorescence intensity with time with the hydrophobic core of the lipid droplets contributing to the observed intensity enhancement.

Investigating the dynamics of different biomolecules in the cellular milieu through microscopic imaging has gained paramount importance in the last decade. Continuous developments in the field of microscopy are paralleled by the design and synthesis of fluorophores that target specific compartments within a cell. In this study, we have synthesized four fluorescent styrene derivatives, a neutral styrylpridine, three cationic styrylpyridinium probes with and without cholesterol tether, and investigated their absorption, emission, and cellular imaging properties.

In the recent years, the reported cases of mitochondrial disorders have reached a colossal number. These disorders spawn a sundry of pathological conditions, which lead to pernicious symptoms and even fatality. Due to the unpredictable etiologies, mitochondrial diseases are putatively referred to as "mystondria" (mysterious diseases of mitochondria).
