The use of sunscreen has become an indispensable daily routine since UV radiation is a critical environmental stress factors for human skin. This study focused on the design, synthesis, thermal/chemical stability and efficacy/safety evaluations of a new heterocyclic derivative, namely LQFM184, as a photoprotective agent. The compound showed stability when submitted under oxidative and high temperature conditions. It also revealed an absorption at 260-340 nm (UVA/UVB), with a main band at 298 nm and a shoulder close to 334 nm. LQFM184 showed capacity to interact with other existing UV filters, promoting an increase in the sun protection factor. In relation to acute toxicity, its estimated LD50 was > 300-2000 mg/kg, probably with a low potential of inducing acute oral systemic toxicity hazard. In addition, our data showed that this compound did not have eye irritation, skin sensitization or phototoxicity potentials. Taken together, these findings make LQFM184 a promising ingredient to be used, alone or in association with other UV filters, in cosmetic products such as sunscreens with a broad-spectrum of protection.

LQFM184:一种新型的宽紫外辐射范围吸收剂化合物

由于紫外线辐射是人类皮肤的关键环境压力因素,因此使用防晒霜已成为必不可少的日常工作。本研究侧重于作为光保护剂的新型杂环衍生物 LQFM184 的设计、合成、热/化学稳定性和功效/安全性评估。该化合物在氧化和高温条件下表现出稳定性。它还揭示了在 260-340 nm (UVA/UVB) 处的吸收,主带在 298 nm,肩带接近 334 nm。LQFM184 显示出与其他现有紫外线过滤剂相互作用的能力,促进防晒系数的增加。就急性毒性而言,其估计 LD50 为 > 300-2000 mg/kg,可能诱发急性口服全身毒性危害的可能性较低。此外,我们的数据表明,该化合物没有眼睛刺激性、皮肤致敏性或潜在的光毒性。综上所述,这些发现使 LQFM184 成为一种很有前景的成分,可以单独使用或与其他紫外线过滤剂结合使用,用于具有广谱保护作用的防晒霜等化妆品中。
