Abstract
Building on previous investigations, structural modifications to the neuronal calcium ion channel blocker MONIRO-1 and related compounds were conducted that included replacement of the amide linker with an aniline and isosteric sulfonamide moiety, and the previously used strategy of substitution of the guanidinium group with less hydrophilic amine functionalities. A comprehensive SAR study revealed a number of phenoxyaniline and sulfonamide compounds that were more potent or had similar potency for the CaV2.2 and CaV3.2 channel compared to MONIRO-1 when evaluated in a FLIPR-based intracellular calcium response assay. Cytotoxicity investigations indicated that the sulfonamide analogues were well tolerated by Cos-7 cells at dosages required to inhibit both calcium ion channels. The sulfonamide derivatives were the most promising CaV2.2 inhibitors developed by us to date due, possessing high stability in plasma, low toxicity (estimated therapeutic index > 10), favourable CNS MPO scores (4.0-4.4) and high potency and selectivity, thereby, making this class of compounds suitable candidates for future in vivo studies.

Bioorg Chem 2024; 142:106962.

Abstract
Two new dimeric Lycopodium alkaloids, casuattimines A and B (1 and 2), along with twelve previously undescribed Lycopodium alkaloids, casuattimines C-N (3-14), and eight known Lycopodium alkaloids, were isolated from Lycopodiastrum casuarinoides. Casuattimines A and B (1 and 2) are the first two ether-linked Lycopodium alkaloid dimers. Casuattimines C and D (3 and 4) are unique Lycopodium alkaloids characterized by a long fatty acid chain. Structural elucidation was achieved through HRESIMS, NMR, and electronic circular dichroism (ECD) calculations. In addition, the absolute configurations of compounds 7, 13, and 14 were determined by single crystal X-ray diffraction. Compounds 1, 2, and 4 demonstrated notable Cav3.1 channel inhibitory activities presenting IC50 values of 10.75 ± 1.02 μM, 9.33 ± 0.79 μM, and 7.14 ± 0.86 μM, respectively. The dynamics of compound 4 against the Cav3.1 channel and preliminary structure-activity relationships of these active Lycopodium alkaloids were also discussed.

Abstract
Saldigones A-C (1, 3, 4), three new isoprenylated flavonoids with diverse flavanone, pterocarpan, and isoflavanone architectures, were characterized from the roots of Salvia digitaloides, together with a known isoprenylated flavanone (2). Notably, it's the first report of isoprenylated flavonoids from Salvia species. The structures of these isolates were elucidated by extensive spectroscopic analysis. All of the compounds were evaluated for their activities on Cav3.1 low voltage-gated Ca2+ channel (LVGCC), of which 2 strongly and dose-dependently inhibited Cav3.1 peak current.

Abstract
Prenylated flavonoids have attracted much attention due to their promising and diverse bioactivities on multitarget tissues. To the best of our knowledge, our recent studies demonstrated first that (2 S)-6-prenylnaringenin (6-PNG), a hop component, blocks Cav3.2 T-type calcium channels (T-channels) and alleviates neuropathic and visceral pain with little side effects; it also indicated first that other natural prenylflavanones (PFVNs), such as sophoraflavanone G and (2 S)-8-PNG, or synthetic 6-PFVNs including (2 R/S)-6-PNG and its derivatives are capable of blocking T-channels and useful for pain therapy. Through the structure-activity relationship studies on the synthetic 6-PFVNs, we identified 6-(3-ethylpent-2-enyl)-5,7-dihydroxy-2-(2-hydroxyphenyl)chroman-4-one (8j or KTt-45) as the most potent blocker of Cav3.2 T-channels. It is interesting to recognize a prenylated flavonoid, belonging to other sub-classes, as a novel T-channel blocker. Therefore, this article will review some of our recent studies to introduce a new branch to researchers studying on prenylated flavonoids.

Effects of the T-type calcium channel antagonist Z944 on paired associates learning and locomotor activity in rats treated with the NMDA receptor antagonist MK-801. Psychopharmacology (Berl) 2018; 235:3339-3350.

Abstract
RATIONALE Currently available antipsychotics are unsatisfactory given their side effects and limited efficacy for the cognitive symptoms of schizophrenia. Many currently available drugs, such as haloperidol, are T-type calcium channel antagonists in addition to their well-established antagonism of dopamine D2 receptors. Thus, preclinical research into the effects of T-type calcium channel antagonists/blockers in behavioral assays related to schizophrenia may inform novel therapeutic strategies. OBJECTIVES We explored the effects of a recently developed highly selective T-type calcium channel antagonist, Z944 (2.5, 5.0, 10.0 mg/kg), on the MK-801 (0.15 mg/kg) model of acute psychosis. METHODS To examine the effects of Z944 on behaviors relevant to schizophrenia, we tested touchscreen-based paired associates learning given its relevance to the cognitive symptoms of the disorder and locomotor activity given its relevance to the positive symptoms. RESULTS Acute treatment with Z944 failed to reverse the visuospatial associative memory impairments caused by MK-801 in paired associates learning. The highest dose of drug (10.0 mg/kg) given alone produced subtle impairments on paired associates learning. In contrast, Z944 (5.0 mg/kg) blocked the expected increase in locomotion following MK-801 treatment in a locomotor assay. CONCLUSIONS These experiments provide support that Z944 may reduce behaviors relevant to positive symptoms of schizophrenia, although additional study of its effects on cognition is required. These findings and other research suggest T-type calcium channel antagonists may be an alternative to currently available antipsychotics with less serious side effects.

Br J Pharmacol 2017; 175:2284-2295.

Abstract
BACKGROUND AND PURPOSE Voltage-gated calcium channels are involved in nociception in the CNS and in the periphery. N-type (Cav 2.2) and T-type (Cav 3.1, Cav 3.2 and Cav 3.3) voltage-gated calcium channels are particularly important in studying and treating pain and epilepsy. EXPERIMENTAL APPROACH In this study, whole-cell patch clamp electrophysiology was used to assess the potency and mechanism of action of a novel ortho-phenoxylanilide derivative, MONIRO-1, against a panel of voltage-gated calcium channels including Cav 1.2, Cav 1.3, Cav 2.1, Cav 2.2, Cav 2.3, Cav 3.1, Cav 3.2 and Cav 3.3. KEY RESULTS MONIRO-1 was 5- to 20-fold more potent at inhibiting human T-type calcium channels, hCav 3.1, hCav 3.2 and hCav 3.3 (IC50 : 3.3 ± 0.3, 1.7 ± 0.1 and 7.2 ± 0.3 μM, respectively) than N-type calcium channel, hCav 2.2 (IC50 : 34.0 ± 3.6 μM). It interacted with L-type calcium channels Cav 1.2 and Cav 1.3 with significantly lower potency (IC50 > 100 μM) and did not inhibit hCav 2.1 or hCav 2.3 channels at concentrations as high as 100 μM. State- and use-dependent inhibition of hCav 2.2 channels was observed, whereas stronger inhibition occurred at high stimulation frequencies for hCav 3.1 channels suggesting a different mode of action between these two channels. CONCLUSIONS AND IMPLICATIONS Selectivity, potency, reversibility and multi-modal effects distinguish MONIRO-1 from other low MW inhibitors acting on Cav channels involved in pain and/or epilepsy pathways. High-frequency firing increased the affinity for MONIRO-1 for both hCav 2.2 and hCav 3.1 channels. Such Cav channel modulators have potential clinical use in the treatment of epilepsies, neuropathic pain and other nociceptive pathophysiologies.

Abstract
(±)-Ganoapplanin (1), a pair of novel meroterpenoid enantiomers featuring an unprecedented dioxaspirocyclic skeleton constructed from a 6/6/6/6 tetracyclic system and an unusual tricyclo[4.3.3.03',7']dodecane motif, were isolated from Ganoderma applanatum. Its structure and absolute configurations were determined by spectroscopic analyses, X-ray crystallography, and ECD (electronic circular dichroism calculations). A plausible biogenetic pathway, involving a key Gomberg-Bachmann reaction, was also proposed for (±)-1. Biological studies showed that (±)-1 and its enantiomers exhibited different inhibitory activities on T-type voltage-gated calcium channels.
