Her scientific portfolio includes 40 publications indexed in Web of Science and Scopus, supported by 199 citations across 162 documents and an h-index of 8, reflecting her strong research impact. She has completed seven research projects and is an inventor or co-inventor on seven patents focused on bioactive marine compounds and their therapeutic potential. Her research areas span biology, biochemistry, biomedicine, natural biologically active substances, and preclinical trials, with collaborative work involving Far Eastern Federal University in Vladivostok. Dr. Klimovich has contributed significantly to the characterization of marine peptides and metabolites, including the sea anemone peptide HCRG21, which exhibits analgesic, anti-inflammatory, and anxiolytic activities and demonstrates therapeutic potential for allergic dermatitis and psoriasis. She has also studied the peptide HCIQ2c1 with anti-inflammatory and neuroprotective properties, and the sea anemone peptides Hcr 1b-2, Hcr 1b-4, and AnmTX Sco 9a-1, which show strong anxiolytic, anti-inflammatory, and analgesic effects. Her work further includes discovering the antidiabetic and antiglycemic activities of the peptide Mgf, evaluating antimicrobial and antitumor effects of phenylphascaplysine alkaloid derivatives, and identifying the ability of triterpene glycosides from sea cucumbers—Cucumarioside A0-1, Djakonovioside A—and the peptide Hct-S3 to inhibit tumor metastasis. Additionally, she contributed to demonstrating that asterripeptides A–C from marine fungi possess therapeutic activity in treating infected wounds. Her research advances marine-derived therapeutic discoveries with high relevance to pharmacology, biotechnology, and translational biomedicine.
