Background: This study investigates the compatibility and stability of active pharmaceutical ingredients (APIs) in Cleoderm™, a dermatological cream designed for the treatment of acne vulgaris, hyperpigmentation, dermatitis and other skin conditions. Cleoderm™ is formulated with hyaluronic acid and Cleome gynandra L., recognized for their sebum-regulating and anti-inflammatory properties. Complementary ingredients, such as palmitoyl tripeptide-8, bisabolol, and functional oils, contribute to the cream's antioxidant and anti-inflammatory effects.
Method: High-performance liquid chromatography (HPLC) was employed to assess the compatibility of APIs in Cleoderm™. Forced degradation studies were conducted to evaluate API stability under diverse stress conditions.
Result: The study established beyond-use dates (BUDs) for the tested formulations stored at room temperature. Adapalene (0.1%), dapsone (5% to 10%), and hydroquinone (10%) exhibited BUDs of 180 days. Throughout this period, no discernible physical alterations were observed in the formulations, and their chemical stability remained within acceptable parameters. Comprehensive microbiological assessments affirmed the efficacy of the preservative system.
Conclusion: These findings underscore Cleoderm™'s potential as a dependable vehicle for compounded dermatological preparations. The study underscores the significance of continuous stability assessments and quality control protocols in formulating personalized and efficacious treatments for acne vulgaris and other inflammatory dermatoses. Progress in this field holds promise for enhancing therapeutic options and outcomes for individuals affected by these conditions.

The widespread application of genome editing to treat and cure disease requires the delivery of genome editors into the nucleus of target cells. Enveloped delivery vehicles (EDVs) are engineered virally derived particles capable of packaging and delivering CRISPR-Cas9 ribonucleoproteins (RNPs). However, the presence of lentiviral genome encapsulation and replication proteins in EDVs has obscured the underlying delivery mechanism and precluded particle optimization.

Recurrent missense mutations in the human epidermal growth factor receptor 2 (HER2) have been identified across various human cancers. Among these mutations, the active S310F mutation in the HER2 extracellular domain stands out as not only oncogenic but also confers resistance to pertuzumab, an antibody drug widely used in clinical cancer therapy, by impeding its binding. In this study, we have successfully employed computational-aided rational design to undertake directed evolution of pertuzumab, resulting in the creation of an evolved pertuzumab variant named Ptz-SA.

Despite recent advances in cancer treatment, there is still a need for novel compounds with antineoplastic activity. Among 11 biphenyl-based organogold(III) -heterocyclic carbene (NHC) (BGC) complexes of general formula [(C^C)Au(NHC-pyr)X], where (C^C) = 4,4'-ditertbutylbiphenyl, X = Cl or phenylacetylide, and (NHC-pyr) is a pyridyl-substituted NHC ligand, the complex bearing a 4-CF-pyridyl substituent and a chloride ligand showed promising antineoplastic activity on the triple negative breast cancer cell line. was able to induce cell apoptosis but had no effect on the cell cycle.
