We describe the synthesis and results of biological evaluation of newly designed 2,4,6-trisubstituted symmetrical 1,3,5-triazine (TAZ) derivatives. Among the tested trisubstituted TAZ derivatives, some CS-symmetrical alkoxy-amino-substituted TAZ derivatives, including 7ggp and 6dpp, showed significant antiviral activity against herpes simplex virus type 1 (HSV-1). The compound with the highest level of antiviral activity was C3-symmetrical trialkoxy-TAZ derivative 4bbb, which showed a considerably high selectivity index (IC50/EC50=256.6). The structure-activity relationships for anti-HSV-1 activity of the tested 2,4,6-trisubstituted TAZ derivatives are also described.

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.

In triple-negative breast cancer (TNBC), pro-tumoral macrophages promote metastasis and suppress the immune response. To target these cells, a previously identified CD206 (mannose receptor)-binding peptide, mUNO was engineered to enhance its affinity and proteolytic stability. The new rationally designed peptide, MACTIDE, includes a trypsin inhibitor loop, from the Sunflower Trypsin Inhibitor-I.

Mechanical stress modulates bone formation and organization of the extracellular matrix (ECM), the interaction of which affects heterotopic ossification (HO). However, the mechanically sensitive cell populations in HO and the underlying mechanism remain elusive. Here, we show that the mechanical protein Polysyctin-1 (PC1, Pkd1) regulates CTSK lineage tendon-derived mesenchymal stem cell (TDMSC) fate and ECM organization, thus affecting HO progression.

Article Synopsis
- Immune checkpoint therapies have revolutionized cancer treatment but face challenges like low response rates and drug resistance, highlighting the need for a better understanding of the tumor microenvironment (TME).
- Recent studies show that biomechanical forces within the TME significantly impact immune responses and tumor progression, indicating that manipulating these forces could enhance immune activation against tumors.
- The review discusses key biomechanical mechanisms, the role of the extracellular matrix, and potential clinical applications, aiming to provide insights for discovering new therapeutic targets.
The Loss of Tafazzin Transacetylase Activity Is Sufficient to Drive Testicular Infertility.

Barth syndrome (BTHS) is a rare, infantile-onset, X-linked mitochondriopathy exhibiting a variable presentation of failure to thrive, growth insufficiency, skeletal myopathy, neutropenia, and heart anomalies due to mitochondrial dysfunction secondary to inherited TAFAZZIN transacetylase mutations. Although not reported in BTHS patients, male infertility is observed in several () mouse alleles and in a mutant. Herein, we examined the male infertility phenotype in a BTHS-patient-derived point-mutant knockin mouse () allele that expresses a mutant protein lacking transacetylase activity.
