Aromatase plays a crucial role in the conversion of androgens to oestrogens and is often overexpressed in hormone-dependent tumours, particularly breast cancer. [18F]BIBD-071, which has excellent binding affinity for aromatase and good pharmacokinetics, has potential for the diagnosis and treatment of aromatase-related diseases. The MCF-7 cell line, which is hormone receptor-positive (HR+), was used in the assessment of the novel [18F]-labelled radiotracer [18F]BIBD-071 via positron emission tomography (PET) imaging of an HR+ breast cancer xenograft model.

Overexpression of the gonadotropin-releasing hormone receptor (GnRH-R) plays a vital role in the advancement of reproductive malignancies such as ovarian, endometrial, and prostate cancer. Peptidomimetic GnRH antagonists are a substantial therapeutic development, providing fast and reversible suppression of gonadotropins by directly blocking GnRH-R. Unlike typical GnRH agonists, these antagonists prevent the early hormonal flare, have a faster onset of action, and have a lower risk of cardiovascular problems.

Background: Current treatment strategies for hormone-dependent breast cancers, including adjuvant endocrine therapy, often fail due to persistence of breast cancer stem cells (brCSCs), which are significant contributors to tumor recurrence and treatment resistance. Therefore, gaining deeper insights into the molecular regulators driving breast cancer aggressiveness is important. Moreover, given the complexities and expenses involved in developing new pharmacological agents, the strategic repurposing of existing FDA-approved drugs to target these key molecular pathways presents a compelling approach for identifying novel therapeutic interventions aimed at mitigating tumor refractoriness.

Breast cancer is one of the most common cancers found in women worldwide. Besides the availability of clinical drugs, drug resistance and considerable side effects are concerning issues driven the needs for the discovery of novel anticancer agents. Aromatase inhibition is one of the effective strategies for management of hormone-dependent breast cancer.

Progesterone (P4) is a vital female sex hormone involved in various physiological processes, including the maintenance of the endometrium, mammary gland development, and bone health. Beyond its reproductive roles, P4 is implicated in the pathogenesis of hormone-dependent conditions like uterine fibroids, the most common benign tumors in women, which can severely affect quality of life and fertility. Traditionally, estrogen was considered the primary driver of fibroid growth, but recent research highlights the significant role of P4 in fibroid growth.
