Wewakazole B, A New Cyclic Dodecapeptide from the Red Sea Cyanobacterium Moorea producens

Japanese, Cyanobacteria are prolific sources of novel bioactive compounds. The chemical profiles we obtained using LC-MS and checked with the MarinLit database showed that there are potential new compounds from Moorea producens samples obtained from the Red Sea. In this presentation the isolation and structure elucidation of a new cyclic dodecapeptide, wewakazole B (1), is reported.

The brownish-red filamentous sample was obtained by SCUBA near Jeddah, Saudi Arabia. A small portion of the sample was preserved in RNAlater and identified as M. producens by standard 16S rRNA gene sequencing using cyanobacteria-specific primers 106F and 1509R, and internal primers 359F and 781R (Martinez-Murcia et al., 1995; Nubel et al., 1997). The bulk of the sample was extracted with methanol followed by solvent partition using EtOAc and water, then, BuOH. These extracts were tested for antifouling activity against the barnacle larvae Amphibalanus amphitrite, cytotoxicity against MCF-7 breast cancer cells, and trypsin inhibition. LC-MS was carried out in parallel for dereplication in conjunction with the MarinLit database. The extracts were found to be inactive but a unique [M+H]⁺ m/z of 1127 was detected in the EtOAc extract and was pursued. A series of open column chromatography and HPLCs afforded 0.4 mg of 1.

The molecular formula, C₅₈H₇₀N₁₂O₁₂, determined by HRESIMS ([M+H]⁺ m/z1127.5310, ∆ = 0.39 ppm), suggested thirty unsaturations. Dereplication using mass and ¹H NMR data showed wewakazole (Nogle et al., 2003) as the nearest candidate. HSQC, COSY, and TOCSY revealed nine common and three modified amino acid residues which were connected by HMBC and ROESY correlations acquiring five fragments. Connections to the oxazole and methyloxazole fragments proved to be a challenge due to the lack of correlations towards neighboring amino acids. All possible combinations were considered that lead to the most logical planar structure and cyclic sequence. Chiral LC-MS and HPLC analysis showed that all amino acid residues possess the L- configuration. The wewakazoles are the only cyclic peptides from marine cyanobacteria having both Oxz and MeOxz. Their function and bioactivity require further investigation.

Japanese, The genus of red alga Laurencia is one of the richest producers of halogenated compounds (mostly brominated) ³⁾. Murai et al ⁴⁾ and Butler et al ⁹⁾ showed enzymatic bromination of Laurencia C₁₅acetogenins including laurencin (1) ^1,2)and sesquiterpenoids snyderols using partially purified bromoperoxidase (BPO) from L. nipponica and vanadium-dependent BPO (VBPO) from a mixture of red algae including L. pacifica. However, since the lack of information of sequences, the structural information and biochemical aspects of BPO from L. nipponica and VBPO from L. pacifica remains unknown. Here, we report cDNA cloning of VBPOs from L. nipponicaand in vitro enzymatic bromination of putative biosynthetic precursors using recombinant enzymes.

Two VBPOs (LnVBPO1 and LnVBPO2) were cloned from L. nipponica and recombinant LnVBPOs were prepared. Recombinant LnVBPOs were subjected to enzyme activity assay. A general substrate, monochlorodimedone (MCD), was utilized for K_m determination for H₂O₂ and , essential for bromination of organic substrate. K_m for H₂O₂was 0.03 mM in both LnVBPOs, K_m for were 0.53 mM for LnVBPO1 and 0.35 mM for LnVBPO2, respectively. A derivative of putative precursor of laurencin (1), TMS-capped (3E, 6R, 7R)-laurediol (4) was subjected to LnVBPOs enzymatic bromination and gave similar MS/MS spectrum of deacetylaurencin (3). Since the compound 3 is considered to be the final precursor of 1, it is suggested that VBPO catalyzes bromination in Laurenciametabolites.

We also cloned VBPOs from other Laurencia spp. which produce brominated sesquiterpenoids (L. okamurae) and triterpenoids (L. saitoi). We will discuss in vitro enzymatic bromination of these two LaurenciaVBPOs.

Vanadium dependent bromoperoxidase (VBPO) was cloned from the red alga Laurencia nipponica which produces a halogenated compound, laurencin. The enzyme catalyzed cyclization and bromination of a precursor of laurencin. Bromination activity of recombinant enzyme was investigated. A similar type of VBPO was cloned from L. okamurae which produces a halogenated sesquiterpenoid, laurinterol. The recombinant enzyme showed bromination activity. In addition, another type of VBPO was cloned from L. saitoi which produces a halogenated triterpenoid. Its properties were investigated by using its recombinant protein. The structure of bromoallene containing C15 compound, omaezallene was reported. Its totaly syntehsis was successfully achieved.
