Abstract
Since early 2020, disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global pandemic, causing millions of infections and deaths worldwide. Despite rapid deployment of effective vaccines, it is apparent that the global community lacks multipronged interventions to combat viral infection and disease. A major limitation is the paucity of antiviral drug options representing diverse molecular scaffolds and mechanisms of action. Here we report the antiviral activities of three distinct marine natural products─homofascaplysin A (1), (+)-aureol (2), and bromophycolide A (3)─evidenced by their ability to inhibit SARS-CoV-2 replication at concentrations that are nontoxic toward human airway epithelial cells. These compounds stand as promising candidates for further exploration toward the discovery of novel drug leads against SARS-CoV-2.

Abstract
A diterpene (1), previously isolated from a Japanese marine sponge, together with two undescribed (2, 3) diterpenes with highly rearranged carbon skeletons have been characterized from the Australian nudibranch species Goniobranchus geometricus. The structures and relative configuration were determined by spectroscopic analyses informed by detailed molecular modeling, as well as by DFT, DP4, and coupling constant predictions. A 13 R,14 R configuration was determined for secoshahamin (1) by chemical correlation with 12-desacetoxyshahamin C (4) and 12-desacetoxypolyrhaphin A (5); each metabolite (1, 4, and 5) was subjected to saponification and lactonization, yielding the same δ-lactone product (6). Secoshahamin has the same carbon skeleton as a putative precursor that may play a key role in the biosynthesis of highly rearranged diterpenoid scaffolds via C-9/C-11 cleavage of a spongian diterpene precursor.

Abstract
Results of model studies demonstrating a stereoselective synthetic route to tricyclic analogues of the bis(piperidine) alkaloid xestoproxamine C are presented. Dearomatization of a tricyclic pyridine derivative to afford an alkylidene dihydropyridine (anhydrobase) intermediate followed by catalytic heterogeneous hydrogenation was used to install the correct relative stereochemistry about the bis(piperidine) ring system. Other key features of these model studies include development of an efficient ring-closing metathesis procedure to prepare macrocyclic derivatives of 3,4-disusbstituted pyridines, intramolecular cyclizations of alkylidene dihydropyridines to establish pyridine-substituted pyrrolidines and piperidines, successful homologation of pyridine-4-carboxaldehydes using formaldehyde dimethyl thioacetal monoxide (FAMSO), and application of B-alkyl Suzuki coupling to assemble substituted pyridines.

Abstract
A new 3-alkylpiperidine compound (–)-acanthocyclamine A (1) has been obtained from the methanolic extract of Acanthostrongylophora ingens (order Haplosclerida, family Petrosiidae) collected from Wakatobi Marine National Park in South East Sulawesi, Indonesia. The structure of 1 was investigated by extensive 1D- and 2D-NMR experiments. The absolute configuration of 1 was established by X-ray crystallography from anomalous dispersion effects using Cu radiation as C2 (R), C3 (R), C7 (R), and C9 (R). A plausible biosynthetic scheme leading to 1 is presented, and compared with the biosynthetic pathway proposed for the manzamine alkaloids.

Abstract
The absolute structures of R-(-)-2-methylpiperazine (rmpip), S-(+)-2-methylpiperazine (smpip), R-(-)-2-methylpiperazinediium dibromide (rmpipBr) and S-(+)-2-methylpiperazinediium dibromide (smpipBr) have been determined by anomalous dispersion employing the Parsons' Q and Hooft methods. The studies were undertaken to determine the limitations of the absolute structure determination of light element structures (C, H, N) employing routine single-crystal X-ray diffraction laboratory conditions. The structures of the neutral methylpiperazines were known from a priori non-crystallographic methods and were confirmed by the absolute structure determination of their dibromide salts. By employing the full data collection of Bijvoet pairs and minimizing systematic errors, the absolute structure parameters 0.09 (8) (Hooft) for R-(-)-2-methylpiperazine and 0.05 (8) (Hooft) for S-(+)-2-methylpiperazine were determined.

Abstract
The relative configuration of the plakortolide metabolite (4) isolated from a Madagascan Plakortis sp. and named (+)-plakortolide I is revised following reassignment of the ¹³C signals for C-7 and C-16, thereby establishing that the metabolite isolated was likely (+)-plakortolide E (3). We propose that the name "plakortolide I" should be retained for the plakortolide metabolite 5 first isolated by the Faulkner group; its enantiomer 4 can then be named ent-plakortolide I in line with the description of Barnych and Vatèle. The spectroscopic data for MPA esters prepared from synthetic samples of seco derivatives of plakortolide E (3) and ent-plakortolide I (4) were compared with those of MPA esters of seco derivatives from naturally isolated plakortolides L (1) and K (2) and of seco-plakortolide E (6a). Likewise, the spectroscopic data for MTPA esters derived from 3 and 4 were compared with data for the MTPA esters derived from 5. These various comparisons established that the sign of the specific rotation associated with the natural isolates is an unreliable indicator of absolute configuration and verify that the absolute configurations of plakortolides L (1), K (2), E (3), and I (5) are (3S, 4S, 6S), (3R, 4R, 6S), (3R, 4R, 6R), and (3S, 4S, 6R), respectively.

Abstract
Compounds 2-5, incorporating various elements of the 3,4'-bis(piperidine) core associated with the sponge-derived alkaloid haliclonacyclamine A (HA, 1), have been prepared through, inter alia, aldol-type reactions of N-substituted piperidin-4-ones and certain derivatives. Screening of these compounds in various assays, including an ecological one, reveals that compound 5 exhibits allelochemical properties similar to those associated with HA itself.

Abstract
The complete stereostructures of xestoproxamines A-C, from the Bahamian sponge Neopetrosia proxima, were assigned from spectroscopic analysis, including MS, 2D NMR, and integrated degradation-CD analysis. Two new CD application protocols are described for defining absolute configuration: one for allylic methyl groups in branched chains and a second for the heterocyclic core bis-piperidine with specific applicability to other members of this class alkaloids--known for their stereoheterogeneity--and tertiary cyclic amines in general.

Abstract
A new tetracyclic bis-piperidine alkaloid, neopetrosiamine A (1), has been extracted from the marine sponge Neopetrosiaproxima collected off the west coast of Puerto Rico. The structure of compound 1 was elucidated by analysis of spectroscopic data coupled with careful comparisons of its (1)H and (13)C NMR data with those of a well-known 3-alkylbis-piperidine alkaloid model. The new alkaloid displayed strong in vitro cytotoxic activity against a panel of cancer cell lines as well as in vitro inhibitory activity against the pathogenic microbes Mycobacterium tuberculosis and Plasmodium falciparum.
