DHP compounds exhibit chirality-specific antagonistic or agonistic effects. The structure of rabbit Cav 1.1 bound to an achiral drug nifedipine reveals the general binding mode for DHP drugs, but the molecular basis for chiral specificity remained elusive. Herein, we report five cryo-EM structures of nanodisc-embedded Cav 1.1 in the presence of the bestselling drug amlodipine, a DHP antagonist (R)-(+)-Bay K8644, and a titration of its agonistic enantiomer (S)-(-)-Bay K8644 at resolutions of 2.9-3.4 Å. The amlodipine-bound structure reveals the molecular basis for the high efficacy of the drug. All structures with the addition of the Bay K8644 enantiomers exhibit similar inactivated conformations, suggesting that (S)-(-)-Bay K8644, when acting as an agonist, is insufficient to lock the activated state of the channel for a prolonged duration.The subacute cutaneous lupus erythematosus (SCLE) is a distinct subtype of lupus erythematosus (LE) representing specific clinical and serological features. Almost 20%-30% of the cases with SCLE are predicted to associated with medications. Thiazide diuretics, terbinafine, antiepileptic, and proton pump inhibitors are the best-known drugs to induce drug-related SCLE. Herein we want to present a 65-year-old female with alendronate induced SCLE, resistant to classical therapies, and respond well to intravenous immunoglobulin (IVIG), suggesting that IVIG could be an alternative treatment in patients resistant to classical treatment protocols.Smart photochromic and fluorescent products can respond to an external stimulus by changing their colour and emission spectra with light.
