      <title>⁯</title><p><bold><italic>Dear Editor,</italic></bold></p><p>Wogonin (5, 7-Dihydroxy-8-methoxy flavone) is a traditional naturally occurring flavonoid derived from the root extract of Chinese medicine, named <italic>Scutellaria baicalensis </italic>Georgi. Wogonin contains various biological properties which include allergic diseases, anti-cancer therapy, and anti-inflammatory activities. Wogonin also shows the effects of removing toxins and cleansing the heart (Ancuceanu et al., 2019[<xref ref-type="bibr" rid="R1">1</xref>]). The anticancer therapeutic activity of wogonin has been shown by the regulation of different cell signaling pathways, which includes protein kinase B pathway (serine-threonine kinase) and AMP-activated protein kinase pathways (Bei et al., 2020[<xref ref-type="bibr" rid="R2">2</xref>]). Wogonin also shows positive therapeutic anticancer effects in breast cancer by inhibiting the 5-LO&#x2F;BLT2&#x2F;ERK&#x2F;IL-8&#x2F;MMP-9 signaling cascade and establishes a major pharmacological anticancer activity (Bibi et al., 2019[<xref ref-type="bibr" rid="R3">3</xref>]). Current biological and pharmacological updates on wogonin have been reviewed (Table 1<xref ref-type="fig" rid="T1">(Tab. 1)</xref>; References in Table 1: Du et al., 2019[<xref ref-type="bibr" rid="R4">4</xref>]; Ewendt and Foller, 2019[<xref ref-type="bibr" rid="R5">5</xref>]; Fang et al., 2019[<xref ref-type="bibr" rid="R6">6</xref>]; Gao et al., 2019[<xref ref-type="bibr" rid="R7">7</xref>]; Gharari et al., 2020[<xref ref-type="bibr" rid="R8">8</xref>]; Hanioka et al., 2020[<xref ref-type="bibr" rid="R9">9</xref>]; Hong et al., 2020[<xref ref-type="bibr" rid="R10">10</xref>]; Huang et al., 2020[<xref ref-type="bibr" rid="R11">11</xref>]; Jiang et al., 2019[<xref ref-type="bibr" rid="R12">12</xref>]; Jiao et al., 2019[<xref ref-type="bibr" rid="R13">13</xref>]; Khan and Kamal, 2019[<xref ref-type="bibr" rid="R14">14</xref>][<xref ref-type="bibr" rid="R15">15</xref>]; Khushdil et al., 2019[<xref ref-type="bibr" rid="R16">16</xref>]; Kim et al., 2019[<xref ref-type="bibr" rid="R17">17</xref>]; Kong et al., 2019[<xref ref-type="bibr" rid="R18">18</xref>]; Liang et al., 2019[<xref ref-type="bibr" rid="R19">19</xref>]; Liau et al., 2019[<xref ref-type="bibr" rid="R20">20</xref>]; Luo et al., 2019[<xref ref-type="bibr" rid="R21">21</xref>]; Oomen et al., 2020[<xref ref-type="bibr" rid="R22">22</xref>]; Tan et al., 2019[<xref ref-type="bibr" rid="R23">23</xref>]; Wang and Cui, 2019[<xref ref-type="bibr" rid="R24">24</xref>]; Wang et al., 2019[<xref ref-type="bibr" rid="R25">25</xref>][<xref ref-type="bibr" rid="R26">26</xref>]; Wang et al., 2020[<xref ref-type="bibr" rid="R27">27</xref>]; Xing et al., 2019[<xref ref-type="bibr" rid="R28">28</xref>][<xref ref-type="bibr" rid="R29">29</xref>]; Zhang et al., 2019[<xref ref-type="bibr" rid="R30">30</xref>]).</p></sec>
